The idea of DieselRobin is to form teams of three and then play chars in turns, rotating to the next player when certain missions are completed. Each team gets 3 chars to play in parallel which are randomly assigned from a pool of nominated chars (every player nominates one).
I'll be running this in the channel ##dieselrobin on chat.freenode.net with a bot, Kramell, which will keep track of your scores and make progress announcements when you complete missions. To sign up, get yourself a team of three and pick a team name, then go to ##dieselrobin and enter:
$signup <team name>
and it will sign you up to that team using your IRC nick.
If you can't find a team and/or want to be randomly grouped with some other players then tell me here or in ##dieselrobin. I'll do the grouping initially on the 5th, and after that as I get requests. After you've been grouped you can pick a team name together and sign up in ##dieselrobin as above.
Signups close on the 12th, and DieselRobin starts at 0 AM the 13th of August UTC and ends at the same time on the 28th of August.

For getting on freenode IRC you can use the web client or another client of your choice.
Feel free to leave a comment if you are intending to participate, so I can know how many people there'll be (you still need to sign up on IRC after getting a team though).
