I also think that you should divide the forum in at least 2 parts: one for the development (ideas about new weapons, unspecific bugs etc) and one for personal problems (where users can mainly help each other).
U4e is getting quite huge. I mean that there are always "little" things someone want to know (I just realized that I'm able to shoot a lightning BALL with the Zapper - didn't know that before). Those things are better discussed by the users themselves as I guess they start to annoy the developers...
