TOMEM  I take it back. There is an uninstaller integral with the installer. And VirusBarrier plays MUCH better with other processes than MacAfee VirusScanner, BY FAR! And it gives much better feedback on the process of scanning.   
(Version 10.5.5)

TOMEM  VirusBarrier sounds about like VirusScan (VIREX), only without an uninstaller. It seems the Mac community is in need of virus cure that is not worse than the illness! Developer opportunity, anyone?   
(Version 10.5.5)

TOMEM  The installer worked right for me, first try, and the programs run at least as well as they did before, though I haven't checked out everything.

The last update fixed the notorious problem where old files had their last modified date changed when they were simply opened. Hopefully some of the stability issues will be corrected with this update.

Whatever one thinks of Office and MS, nothing can touch the Word outliner/TOC tool. If you are a serious writer of structured documents, you can go to FrameMaker or InDesign, but that's a whole other level of expense and complexity. I would cheer heartily if Pages, Mellei or others were to imitate the Word outliner!! AppleWorks never got it right, and neither have any of the others.   
(Version 12.1.5)

TOMEM  It would be a lot better if it didn't make it impossible to rename a file in the Finder. It still renders the cursor and highlighting inoperative when renaming files. I have to close the Finder window and open a new one to get it to work again, and then only briefly. Unacceptable.   
(Version 2.1)

TOMEM  One of the best pieces of software ever! Put me over the hump of doing a full automated backup daily, because it is just so easy and foolproof.

And it finds corrupted files that Disk Utility can't find.

THE solution to backup onto external hard drives...   
(Version 2.1.4)

TOMEM  Great took and I've been a long time user, but the last couple of revs have really got problems:

* slow transfer rates way below my network limits.

* failure to complete transfers, hanging with beachball, has to be force quit.

* No old versions available on the web site.   
(Version 2.7.3)

TOMEM  Great initial experience.

Downloaded, installed, up and running and installed and unsupported program that runs just fine. Total time investment about 20 min. Either I'm exceedingly lucky or this is the best thing ever to come along. Imagine! Run Windows software without having to buy and run Windows! This is the way running Windows software on a Mac should be!   
(Version 6.0)

TOMEM  Awwww.... PPC only!   
(Version 1.1b2)

TOMEM  I'm pretty sure this is the first update EVER that required me to repair privileges before I could get my machine to boot after the update was complete. Maybe it was all those warnings that one should do that BEFORE doing the update?   
(Version 2006-007)

TOMEM  I was taken aback by the lack of a demo, but for $10 it seemed worthwhile when the compared to either $399 for a commercial product or burying one's head in pages of procedures for the weekend. It was up and running in 5 minutes and the online documentation is written at just the right level. There is even a helpful tool for relaying through your ISP mail server when that is required... I have yet to explore IMAP, but that really makes sense for one's own mail server, doesn't it!

Recommended.   
(Version 1.2.2)

TOMEM  Are there plans to include a checkbox to "add to menu" when choosing a destination folder? That would be a very natural place for users to add items to their menu, and is a feature I'd much like to see...   
(Version 1.7.1)

TOMEM  I just noticed it DOES support SFTP! WOW! Outstanding. What a great tool....   
(Version 2.1.3)

TOMEM  I've been looking at NoteTaker, NoteBook, VoodooPad, Journler, viJournal. NoteTaker could use some tweaks, but if you want all these things in one tool, it can't be beat:

* Daily Journaling (not in Notebook, VoodooPad)

* Daily To Do list management (not in VoodooPad, viJournal, Journler)

* Light database note storage, categorizatoin, hyperlinking, report generaton. (not in Journler, viJournal)

* A clipping service for gathering notes from other apps. (not in VoodooPad, Journler, viJournal)

The tweaks I would like to see are a switch to Apple's toolbar configuration tool, a way to generate non-ToDos in a ToDo section (journal entries), and a link interface that defaults to generating a new page titled according to the link text.   
(Version 1.9.11)

TOMEM  I've been playing with Wikipedia, Wikia, VoodoPad, and several free wiki services for months. Excepting VoodooPad, they all seemed klunky, counterintuitive, and hacker-oriented. Now along comes Project Forum (with SSL) or Course Forum (w/o SSL) and it's an epiphany. It's a wiki you download and have up and running in literally 5 min. And then you are immediately busy with the web-only interface figuring out how to organize it to your purposes, with zero learnng curve in terms of getting it to do the basic wiki thing of creating linked pages that anyone can edit.

It's a very different self-contained proprietary approach to wikis that won't appeal to free/open software hounds who relish hacking the thing into existence. It WILL appeal to folks who just want to get on with finding out what a wiki can do for collaborative efforts. And for what it does, the price is reasonable, particularly when SSL is omitted in the eduacational version.

Of course the real epiphany is a web page that can be edited in place by the viewer using a browser. Why no one thought that was important for the first 15 years of the web, I cannot imagine. Having brought 5 or 6 project groups into existence in one day and one weekend of fiddling around, I can't imagine having much interest in any other web site creation approach in the future. No more color coded html! No more SFTP tools or reloads. Hit save changes, and the page appears. This changes everything in a way comparable to the first text editors!

A few more detailed impressions:

* zero user interface application; everything is done via a browser.

* you may need some help proxying the server so that it works with your existing port 80 web server. Each setup differs enough that general instructions are not quite general.

* site changes are reported with page names (or full contents if security not an issue) in automatic RSS feeds. Monitor activity with an RSS news reader. How cool is that!?

* image and file attachment uploads of course!

* tagging text as a link automatically creates a page of the same name

* supports wikis within wikis that are within the site, each administered separately.

* excellent online help, with hint buttons in critical places, downloadable userguide, and FAQ in depth.

* Online forum and email support are very responsive.

Downsides:

* minor problems with different browsers; alignment or graphics.  
(Version 5.1.2)

TOMEM  Peer to peer networking is ok for those who are happy with it, but this isn't what the internet was designed for. It would seem much more powerful and valuable to me if the notebooks were saved into a network viewable and editable format on a plain vanilla FTP or WebDAV site like .Mac. Sure that takes a machine that is continuously online, but otherwise notebook sharing has to be synchronous, which is not going to work very well.

For comparison, check out Projectforum.com, which has a simple but easy-to-use solution for a collaborative server.   
(Version 1.1)

TOMEM  That stinks. Why bother? To be safe(r), I suppose...   
(Version 11.2.6)

TOMEM  Ok, v.1.2.2 corrects the problems I was having with instability of Mail, and adds just about every feature I wished for! So I take back my previous reservations abou this product.   
(Version 1.2.2)

TOMEM  Very important tool, but the implementation is lacking in stability and other amenities. Mailtags has made me realize that email archives should replace or be integrated with the file system because files that are linked to emails are much more useful than those that are filed away in folders. Essentially, linking them to emails provides both the freeform and structured metadata that MacOS pioneered but no one has fully developed. It's gotten to the point where it's worth sending yourself any important file with explanatory material linked in an email.

Despite that, I've had to disable MailTags because it is hanging up Mail.app repeatedly, usually just after sending an email. When restarted, the attempted send is completed, usually. But the inconvenience and threat to my email integrity is simply too serious to be tolerated at present.

As noted by others, MailTags tends to force the widening of the Mail window, which is not all bad unless one is working on a narrow screen. It would be better to provide user options here: choice of horizontal or vertical side panels, which fields to provide as search buttons, ways to shorten their names, etc.

Perhaps Apple will buy and integrate this with their mail tool, and their file system, and thereby pioneer the first mass production file system with full capability metadata.   
(Version 1.2.1)

TOMEM  Didn't work for me:

Bought a new MacBook Pro.

Did fresh install of TeX from Weirden's with iInstallerV2.

Checked it with TexShop, and it works fine on the example files.

Installed and opened PDF Equation.

Tried the example shown in the screen shot. No go. Error message: LaTeX failed to create a PDF file. Maybe your input was invalid?

It crashed once while retrying it.

????   
(Version 0.6)

TOMEM  Kind of cute, but it doesn't measure up in terms of realism of the lava motions. The missing aspect of that is the surface tension dynamics when a new blob is formed and starts moving up, when a blob divides into a cool sinking blob and a rising or hovering blob, and when two blobs merge. In each case, there is a stretching of the blob surface followed by a "pinching off" of one blob from the other, or the reverse during a merger of two blobs. Get out a real one and check it out! Of course adding this would increase the CPU load, but without it, well, it just isn't a lava lamp to me.
