I always met prospective players at a resturaunt or pub. If I advertised on a newsgroup or by flyer, I try to have a phone call before a f-t-f meeting. I ask three questions.
"What keeps you busy during the week?"
- The correct answer is either a job, full-time student, or a combination. I've had some bad experiences with those who are unemployed.
"How would you get to the game?"
- The correct answer is you would drive. Again, bad experiences with those who can not afford their own transportation or those who don't have the wherewithal to obtain a drivers' licence. If I lived in a town where public transportation was a bigger player, than this question might be less inmportant.
"Do you mind small children?"
- The correct answer is "No, I don't mind." I have a yound child who sometimes sits on my lap while I run, and sometimes one of the other players brings over their little ones. My wife provides the child care, but we don't confine them to the playroom.
If that is okay and I get a good feeling, then I meet them at the pub. I tell them that I run a casual game, and it's casual by necessity. We meet at my place, and my wife cooks dinner and other people bring salads and side dishes. We're all 30+ y.o. We have dinner at a mid-game break. We then chat and get to know each other.
If, and only if, they like what they hear from me and I and my wife get a good vibe from them do I invite them over to my house and tell them where I live.
