You have been banned because you misbehaved badly (thread hijacking, thread drift, re-registration, speed-posting). You're not allowed to re-register, so you're not MrUpset nor MrAngry, but MrBeGoneForGood. You haven't been able to post on that board ("
General discussion (no support!)") because on that very board where you tried to post, nobody has permissions to start a new thread. The board description says so, so you could have found out by reading. Let me quote the board description for you:
General discussion for everything that's coppermine-related. Do NOT post support or feature requests here, they should go into the proper boards. Edit 2007-04-11: Locked this sub-board; regular users can't start new threads here.
.There are some sub-board where users can start new threads and others where they can start new threads. You chose the wrong sub-board in the first place. Then you posted some rants about possible security issues without actually saying what you consider to be a security issue. Some other moron (
jimel1981) butted in and posted his totally unrelated stuff in the thread that you already hijacked, because he/she felt encouraged by your silly postings. You answered him in detail (although your answers mostly were wrong), resulting in a match of forum-pong on a totally unrelated issue. You totally crippled the thread you hijacked.
That's why you got banned. You're not allowed to re-register. I don't care what you did on other other forums. On this forum, you're history. Locking, banning the third user account you created.
