With the lose of a dedicated Conan forum at the Mongoose boards (they lost their license, and moved everything to the junk bin), me and Thulsa made a new one at xoth.net.
This is more then just d20 stuff - there are sub-forums for old school rules, other game systems, and other topics. They have been kept them separate, to help navigate by system (this is most beneficial to old school gamers, who could find useful stuff, without having to wade though the sort of endless powergamer stuff, d20 fans tend to posts).
The naming is based on a large city, with each sub-forum name like a city district. It was going to have Sword & Saddles/Planets sub-forums, but a Hyboiran Age theme seems more important.
Its not that big, as it is still new. If anyone is interested, you can join us here:
I tried to access the site, but only got this for my efforts:
