When I joined my Guild, I also attended my first meeting on my own and unfortunately had pretty much the same experience as you. There was, however, one person who made a point of talking with me. I did continue to go but dragged my friends with me so we now have a core group but the membership is starting to warm up. Getting involved and volunteering also will help you meet people and be included. I guess it just takes time but it is certainly an area all clubs should address. I think there are many people we lose because they are not comfortable when they first attend.
