I know, I am at home now and the server is running at work. I can't see the server in the list.
*edit*
Another problem I have is a dynamic IP. I did the !set command, and now my IP has changed. When i join a game I get kicked instantly. I can join as a different user and then change my name back and I get a message "Invalid IP".
Also, what is to stop someone logging on, typing /nick and getting full control?
