There's a problem with accidentally banned IPs since the server restart or something similar...
In case you didn't know, there was a hack attempt and it was shut down. So we've had a blocked IPs due to something that has to do with the restart and things similarly vague and astral.
It happened to me, in any case.
Just PM Koord your IP and he should be able to fix it in a little while.
There's a few threads on this subject, but darned if I can find them right now.
