This WAS a great app, before it was acquired and left to die by current developer. The website of the developer has not been updated in a long time, and I cannot figure out how to get support. The website forum is down, and the developer contact info I haven't been able to find.
The biggest problem I have with this software, and it's HUGE, is that it keeps deleting parts of my posts! UNBELIEVABLE, but true. I discovered it when I went back to my latest entry, and found the last half was missing. At first I thought it was human error ... maybe I had deleted part by mistake. Thankfully I had a backup, and I replaced it. Then, I noticed after I saved the post, that the last half was missing again in the preview window! In HTML code, the last half was just not there. I pasted it back, in HTML mode this time, with all the proper tags. It did it again. Sometimes it would delete a longer or shorter portion. Sometimes, if I didn't edit the file, and clicked on and off the entry, it would reappear ... only to be partially deleted when I opened to edit. Then I looked back through old entries, which happen to include important and personal blog entries, that many of them were partially missing. It was like the app had shot holes in my life story for the last several years. Believe me, I was not happy.
If you value your data, do not buy this version! You may never recover it. I am reporting on version 3.0.2.
I am currently switching over to MacJournal, which unfortunately it not as elegant in some ways, but seems much more polished and is better supported.
