lelping welcome to SR.
One very important thing to remember about AA...... there is only one rule & that rule is that there are no rules!!!!
If you are an alcoholic or think you may be there is only one requirement to be a member of AA and attend any meetings (Except ladies only) and that is a desire to stop drinking.
AA meetings are like people, every meeting has its own personality, keep going to different meetings until you find several that you like.
One very important thing when listening at a meeting is to listen for things that you can relate to, do not try and find differences between your self and those speaking, even though we are alcoholics with many similarities in our stories we are also individuals, you will find in AA people from every walk of life, you will find blacks & whites, athiest, agnostics, Christians, Muslims, & Jews, you will find male & female, the old and the young, but we all have a great deal in common if you relate into AA whether then looking for a way to relate out of AA. Trust me our disease will fight hard to have us relate out because it knows that AA is the solution.
Show up a bit early for meetings and be prepared to stay a bit late, some of the best stuff is before and after the meetings in many cases.
