Well, that popup box is kinda anoying, but thats beside the point. Both the popup box and the link to chat on the main page point to irc.antionline.com. Both times I tried it, I got a server not found error. Isn't it supposed to point to services.antionline.com ?
Anyway, the java client isn't working, but I know the server is up, cause I was just in the channel.
