I gotta side with snowdog and a couple of others here. OCUK is average in my opinion.
Sure i've asked plenty of questions and had good answers for which i'm grateful. I've also had strange answers which have obviously come from kiddies who know no better and ruin the thread.
BUT, its the only forum i'm a member of where you really do not know if what you say may get you banned or suspended. I was suspended in my 1st week without any warning for not totally asterisking out a sweary.....i mean, come on, who reads ALL the rules anyway. I try and respect the rules, but i think OCUK are a little too nazi with theirs. I know its my choice to be here, and for that i adhere to the rules, but having modded and admined on other forums, this is by far the most stringent i've been on.
As for tech advice, i use OCUK, but i mainly use a different site where everyone is really friendly and willing to help. I don't think its attached to a seller, but i daren't post who it is in case i get cyberspanked!
I think gaming forums suck because its populated by fanboi's and kiddies who just flame everyone with l33t and pwn everyone, period!
