i recently installed trac on my work machine to manage my little personal coding projects like the engine behind this site.
trac is a pretty sweet combination of a subversion repository, a wiki, and a bug database. i'm quite impressed with it so far. it was a little painful to get it setup and configured, but it's been nice to me since.
it's up here if you're curious. if you encounter bugs with this site or have suggestions for new features, the best thing to do is to add a ticket through trac.
