At this moment I'm making a module (ok not now because I'm writing and I'm at school, but you get the point) that lets you TPA!!!!!
You think now probably: But how Kroppeb? Simple when you craft a tpa'er you need to chose a 6 digit code (26 letters + 10 numbers = 36 signs => 36^6 = 2176782336 posibilities). The largest problem I have at this moment is that I can't check if a player wants a code that another (ofline) player has chosen. The only thing I can do is check if there are two players online with the same code, but still that isn't an optimal way. So if anyone has an ide of how to do it. I'll be pleased to know.
