Have you ever joined a forum that used FUD software? It stands for "Fast, Uncompromising Discussions." The software is quite old and it seems that there are some people that still use it, though their support forums are quite dead. The look and feel of the software reminds me of the older versions of vBulletin, which perhaps that's who they mainly tried to compete with back in the day. It's still being updated however, and the latest stable release came out back in May of this year. Here's a link to their support forums:
