I know this should be common sense, but this needs to be said for the n00bs.
If you are going to trade invites with people here please use your brain and don't sign up with the same nick that you use here on FST. You will not only lose your account on a lot of trackers but you can get the person who invited you banned or have all their invites taken away.
I recently got all my invites taken away at one of my favorite trackers because some n00b idiot I traded an invite to here used the same name he has here on FST. Nice going
