[/b]I've had 8 consecutive wins whilst being in rank 3 and i haven't ranked up to rank 4. WHY?[b] its because if u loose a game u need more games to reach that rank unless u lost the first game of your stats which don't matter
No. You can only gain points with Normal CPU or Hard CPU and the room must be full. (4 player/CPU). Sometimes if you disconnect or something, it takes a while for that to register so you cannot login again. If you wait a bit, it should work fine. Unless you are trying to log in with someone else's credentials whilst they are still online, in which case, that will be the reason for the message.
Hackers Are Very Annoying... This One Hacker Named Null13 Always Hacks The Chatroom. He Makes The Words So Big You Can Only See About 2 Letters And He Makes It In Annoying Colors >D
Just noticed this, What he did was not a hack, he must have PM'd you using different codes to change your font colour and font size, it is actually quite easy to do.
