Check out the Navbar across the top. Click the link that says "#H2V on IRC."
jcap and I have been working on implementing a way for the members of this site to participate seamlessly into IRC discussion. jcap has installed vBXirc, which does just that. Try it out!
Please note that as this is an official channel for this website, any rules which apply here also apply to the dicussion which takes place in IRC.
