Rick Johnson from Ravensoft just let us know that a new forum dedicated to community mod and map making was created:
"Based on feedback we received at the mod maker round table sessions at QuakeCon, we created a private forum for mod makers. This forum is a place for all mod makers of all engines / games (not just Raven
games) to come and discuss any issues associated with mod making, such as programming, scripting, mapping, modeling, textures, sounds, etc. This forum is only open to people actively involved in making content. If you wish to join, create an account on our forum and then email me with your account name and I’ll give you access. There is also a small website associated with this whole endeavor.
Again, this is for all people making mods for all games / engines."
