From what I understand, the WebChat network acts as experimental network/showcase for Webmaster Inc's Conferenceroom software.
That might explain it's ropey nature :-)
In its defence, there have been periods of several months where it has worked perfectly, though lately it appears as it's gone totally tits up :-(
--- Edit ---
It *does* work right now, though, contrary to popular belief, so feel free to pop in, it's somewhat slow tonight :-)
I recommend a proper IRC client, though, as the web interface kicks you out after 5 minutes of inactivity.
