Philly area adoptive mom support group

Hi all, I've only been thinking about forming a group...I've never done anything like that before. I'm not even a mom yet, but it would be great to have a club like this for adoptive as well as prospective amoms. I was just curious as to how many would be interested in joining an adoptive moms club, if there were one available in the Philly area? It's just so surprising that we live outside of a large city and this type of club/group is hard to come by....other areas around the country, and even the state seem to have at least a few available to join. There are moms clubs, but it would be nice to have a group that is more specific to adoption. Any thoughts on this?
