Private Group Poll

Hey everyone! It seems like most of us were ok with Facebook, but Reddit was offered as another option, so I'll add it here. After we figure out what platform and roughly when, I'll post another thread to discuss vetting of group members. Since we're a pretty small group and don't have too many random drive-by posters, I don't think this will be a major issue, but if we're going to do a private group, I want everyone to be comfortable with those invited to join. Any ideas/suggestions for how to do this are obviously welcome!
