Actually, the Codehaus has an IRC server at irc://irc.codehaus.org, at as a matter of fact there's a channel for Castor. Feel free to join us at any time .... having said that, my presence will be a bit more limited in the next few days due to private circumstances.
Please note that there's an HTTP/HTML daemon available at http:/irc.codehaus.org in case your (corporate) firewalls interfere with your IRC clients.
