If you know how IRC works and use the right security its just taking the same risk as visiting this site.
I think there should be an Invite only IRC.
Those invited can register their nickname on the IRC server, so noone can steal your name of whatever. And the channel itself would require a registered nickname.
IRC is good as long as It has trusted/helpful members. The worst thing about a forum is waiting on a reply, IRC is good in that aspect.
diadora i agree with you plus all of you use socks what the hell you are scared of?
