Hello Torbjörn,
We actually had to take the IRCClient service down due to licensing issues. That said, we'd like to write a new IRCClient service from scratch in ruby, or one that uses libraries that are licensed in an acceptable way (old service was using GPL'd code).
Once we get SDKs & documentation up on the site we can start an open source effort somewhere to build a new IRCClient service that has at least feature parity.
Holler if you'd like to participate in this effort, and I'll keep you up to date on it.
Finally, sorry for pulling the service so abruptly.
very best,
lloyd
