Does anyone know of a location to find out about Pre User Groups?

I have 3 friends that either have a Pre or are getting one soon. They have asked me to help them "modify" their Pre's. (i.e add filecoaster, getting a linux prompt, set up an Ampache server for "Amapche Mobile,...)

I am guessing there are others out there having trouble too? I think it would be neat to meet up at a coffee shop and have a "modify your pre" meeting.

(I would be interested in starting one in Reading, PA or maybe in King of Prussia, PA)

Thanks
