I'd kinda prefer this entire forum was collapsed into 5 or 6 main areas.
yup agreed, i'd start by merging the JOGL and LWJGL forums
since essentially they are both opengl bindings and both set of developers can pretty easily help each other, theres only minor api differences and most problems are related to OpenGL which applies to both bindings.
JOAL is pretty inactive forum and could get away with being merged with the JOGL/LWJGL forums since LWJGL also features OpenAL and again the developers from these bindings can help each other since they are similar api's.
Xith and JMonkey have their own highly active forums on their sites, not sure it makes sense having another for them on JGO, maybe they can be deleted and a link be put to their official forums.
I would also think Android would need a section since its an upcomming java platform (perdictions of 900% growth this year?) it will definietly have lots of games, so a section is a must, maybe have it joined with J2ME.
The above changes would go a long way in streamlining and simplifying the JGO forums.
