What are you talking about, Sio? Ellias is referring to the Message Centre forum - the first one that loads when you hit the "Forum" link at the top of the page.

Other than getting on IRC, this is the closest you will find.

We have a webclient that will allow you to connect; you don't need to download anything additional. The Guide gives links and instructions for the webclient, as well as for a standalone client like mIRC.
