currently i use 3 sites for getting info/help on my modding.
my first one is
www.casemodworld.com it is kind of small and only a few members are active but i still get some good info
my second one is
www.tweaktown.com and there are a lot of active members and a lot of guides/articles so i can get a lot out of them.
and today i joined this one. looks very nice, got a lot of active members and although you somewhat lack in the articles/guides you make up for it by being the first modding site to use an irc channel that ive seen
. hope to use that to get more instant info on some modding projects of mine.
