I've been playing with XOOPS for a few years now, a year and a half ago I put it to use on my site as a member's portal and freeware library. Currently running 2.4.5 probably won't upgrade further until a viable 3.0 is released.

Zeta-Bordeux Theme cobbled together to make for a good navigation platform.

Nothing special, but it does the job.

Find a bug or two and tell me how to fix it. hahahahaha
There's a bound to be a couple.
