well, is it right to say that...

exception = error handling ?

Haha I like the banning part :D. It's cool, but has a flaw. You can't reset it after a certain amount of time, which is bad for people who especially may just have forgotten their password. I also like the verification and security for users too, I never thought of these. I never even thought of a Login class mostly. Haha, this is awesome :D.
