The community is good, depending on how you act.
If you're sensible, reasonably interesting and/or funny, you'll do fine.
And if you're none of that, you won't recieve any angst if you just watch from the sidelines, so to say. :P
However, if you start acting stupid, spamming, breaking Forum rules or leaving yourself open to attack, you're likely to recieve some negative feedback from members of the community.
I suggest you check out different sections of the Forums. They tend to have different ways of acting. You'll quite likely find friendliness in most Help sections of the Forums, or the Modification Discussion topics, or just go to any topic that *Magick* Mage is in. :P
If you're not looking for the cruelty in community, stay away from the Drama section in the Off-Topic Forum for a little bit.
