XeoBB is a web-based forum software package written in PHP that aims for speed, usability and security. Developed in the principle of not re-inventing the wheel, aiming to service as many people as possible reliably and securely.
At the moment, XeoBB is not for mainstream use, and as such, does not have a packaged stable release. Currently it is on the restructuring phase after loosing most of the base code due to subsequent crashes during the past year among other things.
You may browse our source code repository, check out our issue tracker or view our Oholoh project page.
In other words, go and use phpBB or Simple Machines please.
