All discussions for PYPTUG are on the official google group, and joining it is really the only requirement to be a member of PYPTUG:
The discussions will continue to be held there, but some members were asking for event notification through Meetup. Beside that, in an effort to reach more members that might not know about PYPTUG yet, we decided to see if this would improve both the membership and attendance at the meetings.
Don't forget to follow us on twitter, @pyptug
With all of these channels, there is no excuse to not know about an upcoming meeting.
