When you first click the link to join the chat, you can select between several servers. Generally, the first server works fine, but other servers are provided in the case one of them goes down.
Once you choose a server, the client will automatically begin to connect to #rohmacking. The nickname you will join with will be your board username. If it fails, it will not automatically retry. Once you're in, depending on what server you chose, some additional information will be displayed. irc.esper.net will display logon news when you first join, and the other servers will not. Note that it is impossible to use the client to switch to another server mid-session now, as people were abusing the fuction.
