Hi
I imagine that your school is using a firewall to block your connection. Firstly, make sure you are trying to connect to the netgamers server (and not an old server that is no longer running) by typing: /server irc.netgamers.org in the "status" window. If/when that fails to solve your problem, try using a CGI:IRC client, such as
this one, as it might bypass the firewall. I am presently asking people who (should) know more about the problem, however i will post an additional reply here when i hear word from them.
I hope that helps, anyway
