I rebuilt the site from scratch, although I imported all of the old content to maintain the history and archives. I removed or archived some older features that were no longer being used, improved a few of the existing features, and added one or two new ones.
 
New features:
  • mobile-friendly design - should responsively adapt to your phone or tablet
  • removed moderation on forums - new forums should be more spam-resistant, for a little while at least, so your posts should go live quickly
  • speed - everything should be much faster
Retired features:
  • user logins
  • self-posted events - people were just mailing their events to me anyway
  • build your own website
I might bring some of those back, but since they weren't being used much, I'm in no rush.
