I'm currently fairly active on #ubuntu, but other than that, haven't had an opportunity to contribute very much yet.
The only thing I can really list as of yet is having submitted a patch for [https://launchpad.net/distros/ubuntu/+source/joystick/+bug/45930 bug #45930] on the "joystick" package.
To Infinity... and BEYOND!
I'm committed to Ubuntu as my main Desktop. Because of this, I'd like to do what I can to continually improve it. At the moment I'm aiming at eventually becoming a ["MOTU"].
