To connect to #opensolaris, you can use the chat client
which will load below, or find another IRC client
which will run on your machine. Pidgin,
an IRC-capable instant messaging client, is included in many OpenSolaris
distributions; for Developer Express, it's delivered as
/usr/bin/pidgin by the JDS project. If you use the Chatzilla add-on to Firefox, the above channel links should work.
Chat will load here after you input a username and chat name...
Note that if you are behind a firewall, this won't work.
