The IRC channel is where most of the games, discussion and whining goes on, outside of IMing of course.
Those interested in joining in on a game, a casual chat or simply basking on the glow of awesome are welcome to come by, though except for during campaign time, there is no guarentee anyone will be there.
If you are having trouble with the application [logging on tends to be a bit faulty, try just reconnecting a couple times before panicking], then you can connect to the IRC by following the shiny link here.
Once there, our main channel is #dndis.
For those new to IRC;
once you follow the link, click on "Chat NOW!" in the side bar
Type in your user name
Then type the following into the chat window: /j #dndis
Here is the Chatzilla link: irc://irc2.magicstar.net/dndis
See you there!
