I swear there used to be an webIRC client around here someplace. Did someone kill it, or move it, or what?

It can be found here.

Unfortunately, it seems to be down at the moment ... probably due to the recent server migration.

Yes; it will be back sometime in the next couple weeks.

Thank god. I'll be crawling the walls by then.

The IRC server itself is running and can be accessed with any regular IRC client.

And now the web client is back up ... but like most Web <-> IRC gateways, it's not great, so we totally recommend you use a real IRC client.
