Personal Reason:
I am tired of this, I get immature people from TalkFreeLance, that keep join nixism chat, acting like little kids. 3 mins ago, I got the same person join 4 times..

General Reason:
Its a good way, to see who on the forum is interested in what. You can get a general understanding of what members, are interested in what topics, as they would rather view a thread that is interested.
