Keep going to meetings to find one you 'feel' could be your 'home group.'
Pick up this pamphlet on the literature rack at one of the meetings:
Alcoholics Anonymous : Pamphlets
If you 'click' on the pamphlet it will come up in PDF format on line.
and study it and highlight what you believe to be important for you to discuss with a prospective sponsor.
Watch and listen at your meetings. You will start to be able to tell who has worked the steps, who has a sponsor and who 'walks the way they talk'.
And remember, if you do pick one, and find after a bit that the relationship is not the correct one for you, there is no 'law' that says that you cannot get a different sponsor, just as there is no 'law' that says a sponsor cannot let go of a sponsee that that are 'uncomfortable' with.
Keep going to those meetings, more will be revealed to you.
