We have a public forum that is accessible both using XMPP (jabber) or IRC.
Jabber / XMPP

Our jabber server is jabber.logilab.org.
If you don't have a jabber account, create one on a server such as jabber.org (here is a list of free jabber services) or use our web based client.
Once you have a jabber account, come and join us at xmpp://public@conference.jabber.logilab.org
If you do not know what jabber is, read the wikipedia page about jabber
IRC / International Relay Chat
Connect to irc://irc.freenode.net and join #pylint
If you do not know what irc is, read the wikipedia page about irc.
