banani is a simple 2ch-style anonymous message board written in Ruby (with Rails). This is the initial release, so there are some issues, but the features that are there should at least work as expected.

Some issues:
* no documentation except a small help file in
public/help/
* there are no administration capabilities yet
* code should probably be in svn
* no default tags
* there's no test suite

On the other hand, banani is (hopefully) not bloated, uses tagging instead of categories (gotta love tagging), there is a rating system, and tripcodes seem to work as expected.
