I am in full-time ministry. We have a lot of contacts in different parts of the country that we keep in contact with through Facebook, prayer letters, email, and phone. We were able to get nine couples to join our group this year by sending out our group name in our prayer letter, posting it to our personal group page on Facebook, and by following up with some of our friends by phone. None of us were at the same conference, but we all joined the same group, got the same discount, and we were even able to send one couple for free!
