the only other forum i know of is q2players.org and the only reason it hasn't been as active lately was because i was banned, but now im not so beware!
www.q2players.org is ok, but people are just using it for flaming eachother. Nothing really happens there unless there is a topic about cheating or krez, or both of them. But while naymlis was banned I actually took his #1 spot, he always beat me with his spamming. And there are really not that many using the forum, people who asks question have a tendency to be ridiculed instead of given help etc. But check out the columns on q2players at least, they own.The forum on www.fragzone.se (in swedish, so doubt many can read it) used to be fairly active a year back or so, but now it's not. Only other forums I check out is the r1q2 forum and the quakecon forum (when someone talks about q2 there). But this forum has new messages each and every time I refresh the site, and that is quite often. It's scary!
These are my favorite boards (Quake or otherwise) by far.
Well a Q2 server I really enjoyed was 'Kansas DM' - dunno if they had forums though.It seems like they've gone under 'coz I can't connect to them or even detect 'em in Q2 anymore
