I'm looking for a calendar app, preferably an extension or plug-in for Mozilla Thunderbird for Linux. I've used Evolution before, but since I don't use it for email I'd rather not use it. I've done a quick search through the Thunderbird extensions, but didn't see much that was rated very good. It looks like ReminderFox might good, anyone use it? I'm looking for something to set up appointment reminders for one time meetings and recurring weekly meetings. What would you suggest. FYI I'm running Gentoo Linux and Thunderbird 1.07 as 1.5 has not been marked as stable yet.
