Why not do like we do with the South of the River coffee group? No rules, no requirements, just a group of people who get together for coffee on Saturday mornings (or whenever you decide to meet.)
Pick a place that doesn't mind if you hang out for awhile, and preferably doesn't serve really bad-for-you food. Panera doesn't quite fit that bill, we tend to avoid the food but they have a large enough place for us to meet and chat for awhile. We hang out for an hour and a half or so, whatever people have time for. We talk about our triumphs and troubles, give hints and advice, and also plan other fun stuff. It's just a great group of people who have become a surrogate family!
