I setup a discord server for Id Tech 4 related games. It's primarily for modding purposes but I also have a #find-games room. There's also a modding room for Enemy Territory Quake Wars so if anyone still maps for it or wants to talk mods you can go there. We primarily discuss Doom 3.

Since yours seems to prioritize modding, it is welcomed for sure. :-)
