At the moment we are a very loosely organized group, originally formed on meetup.com but now residing primarily (digitally) on Facebook. We currently meet the last Wednesday of each month (with meetup locations and topics announced on the meetup.com website and on our Facebook page.) We try to bring in guest speakers, and also allow brief member presentations for those interested in sharing with the group. There is almost always engaging conversation on a variety of topics. 

We are in the process of getting a bit more formally organized, both in our structure and in affiliation with larger organizations.
