I'm going to use this initially also for nvpy announcements, so you can easily subscribe to be kept up to date. If the discussion traffic grows to more than 2 messages per day, we'll start a new group called nvpy-discuss.
The group should be configured that only your first message is held for moderation (this is to stop spambots). Once the first message has been approved, all subsequent messages will go through without problems.
Let me know at cpbotha at vxlabs.com
if you run into problems!
