Decibel on IRC
I can be found on irc.cuckoo.com as Decibel (when I'm at work), TheCougar (at home), or DeciBull (all over). You can find some irc stats here.
For those who are more familiar with other networks such as EFNet, cuckoonet has a lot more to offer. Nick registration, channel registration, and SSL access are some of the benefits. There's even a relaybot to EFNet available to help ease the transition.
