I love the interface of this application and it's by far the most enjoyable Mac-like IRC client I've used. X-Chat Aqua is too clunky for me, and I had some freakish problems with Colloquy. It's overall a great application for everyday IRC users. However, if you don't plan to buy this soon after you get the trial version, you may be unconvinced well before your 15 days are up regardless of how much you enjoy the application. I will probably purchase this software anyway, but the nagging employed by this application over the course of the 15-day trial is just plain disgusting. The first half or so, it'll be fine and you'll barely even notice, other than the "__ days left. Register today!" text at the top-right which I have no problem with. However, on the eighth day or so, Linkinus will start randomly harassing you to register the software with annoying pop-up messages redundantly alerting you that the software is indeed shareware and giving you two options: "Go", a link to register it, and "Not Yet", which you'd click to continue your trial peacefully... or so you'd think. In the last couple days of the trial, clicking the "Not Yet" button seems to, without warning, disconnect you from all of your IRC connections. It's this type of nagging and harassment from a trial version of software that convinces me not to buy it no matter how much I might love the application, and I can't imagine anyone else being too eager to purchase it after these alerts have annoyed them enough. Deactivating it after 15 days and telling the user to purchase or quit and having a little text thing at the top-right like you already do is more than enough, thank you.
