Upcoming.org is a collaborative event calendar, completely driven by people like you. Enter in the events you're attending, comment on events entered by others, and syndicate event listings to your own weblog.

As Upcoming.org learns more about the events you enjoy, it will suggest new events you never would have heard about.

Thanks to Leonard for rewriting the broken session code that was logging people out every 24 hours or so. Now when you log in, you'll stay logged in! Let us know if you notice any problems with it.

If you want to put Upcoming.org events on your site, try the newly-launched FeedSweep. Just paste the appropriate Upcoming.org "XML" link into FeedSweep, pick your styles, and go!

After a long break, I added iCal calendars for every feed on Upcoming.org. (If you're not a Mac user, try EventSherpa or Mozilla Calendar.) Thanks to George for doing most of the work, and Andre for beta-testing.

Also, ArborBlogs has a great overview of "why you should use Upcoming.org."
