MikeBowler and AlexViggio ran a BOF about XpUserGroups at XpUniverse (July 2001).
There is a mailing list devoted to discussion about these user groups. If you run an Xp User Group or are thinking of starting one then please join us.

why yahoo group? why not a wiki?
It seemed like the simplest thing at the time - MikeBowler
