Just set up my IRC account and hanging around in the beagle-gsoc and scala channels. My nick name is (as always) ordsen. Oddly, my IRC client leaves all joined channels as soon as I minimize it. Should probably make that one work properly.
To log in you can specify your nickname and password in the most IRC clients. To register your nickname follow this guide: https://freenode.net/kb/answer/registration
Just type in the commands shown there into the input line of your IRC client and you should be good to go!
