You would be welcome to just show up at my local guild. There is a membership desk near the door where members sign in and visitors are greeted. They give newcomers information and introduce them to the group. They also take ask them if they are interested in connecting with the various small groups that meet outside of the main guild meeting and put them in touch with people in those groups. I joined but they didn't push me. It's only $25 per year. Some meetings there is a $3 guest fee if it is a national speaker that they paid.
