A box will pop up. Create a nickname for youself, and join server irc.thundercity.net, it might be on the server list, it might not. If not, just add it yourself. If it asks for a port put 6660. Alternatively you can close that grey box and t ype /server irc.thundercity.net

When youre connected, then join the channel flopturnriver by typing /join #flopturnriver
