Updated for Mac users: http://www.ircle.com
. This is for Mac users only, but seems to be fairly up to date, and should help you some as you try to get connected.
I don't know how to configure it for a Mac, but you will need this information:
IRC Network: DALNet (dal.net)
IRC Server: jade.va.us.dal.net (or any other US DALNet server)
IRC Port: 6667, 6668, or 6669 will work (6667 is default - try first)
IRC Channel: #rideguy.com
That, along with the help files from the ircle.com website should get our Mac users connected too. Good luck and hope to see you there!
