i think it would be nice to have a new category with forums for all the major APIs we got: JOGL, JOAL, JInput, LWJGL and Java3D (to keep API questions seperated from general programming).
and perhaps one forum in this category for all the game engines like GAGE or Planetation. (if phpBB allows this there could be sub-forums for each major engine)
Hope many new engines will emerge now that java officially commited to gaming. would be cool to have some concentrated knowledge to compare etc.
