As promised (and with a lot of help from Greg Varnum), I set up the Bug Squad WikiProject: https://www.mediawiki.org/wiki/Project:WikiProject_Bug_Squad
As of this writing, we still need to get some graphics up, but it is a start and has the beginnings of a plan of action. You can sign up now!
I like Tomasz's idea of having mobile-focused bug squad activities. I'd like to get input on how to do this. Because I think it will work best with a low barrier to entry (an area where the KDE bug squad runs into problems), and because the mobile team is running on top of PhoneGap (http://phonegap.com/), I wonder if we couldn't set up a labs instance of the PhoneGap interface.
Tomasz, if we are able to do that, would that allow Bug Squad members to find some bugs without starting up an emulator?
