My choices (in subcategory order only):
FPS:
-CS 1.6 with custom nipper maps.
-KannonBall
-SMS type server, with temp admin accounts on ssh for temp days?
-Brainbread
MMO:
-L2 Free server, with edited rates (like 10x,10x,20x)
-Ragnarok online? meh
Chat:
-IRCd, linked to gamesurge, will boost popularity / publicitiy.
-Ventrilo,
http://www.joe.to offical ventrilo, with all gaming sections, sorted nicely.
Sharing:
-Some kind of sharing server for the community
-DC Hub?
Other:
-SHOUTcast server, (I know myself, bl4nk, and knoid were up for this)
-Image / email host?
-anything else I missed?
I dunno, I would prefer the "chat/other" sections myself. To expand the ways of this community even farther, besides gaming because people are pretty content atm. Just join all the MMO players on one vent or something, since a large % of the j2 now is obsessed with mmos.
Just my opinion.
