When I went to my first Alanon meeting there was a woman there that introduced herself (a long time member) to me as a double winner - which she explained as being part of both alanon and AA. She kept her input and sharing limited to the alanon stuff at the alanon meetings. I've only been to one alanon meeting/group so not sure how others handle it.
ETA: after reading sailorjohn's post I wanted to add that I never said anything other then my first name at my meeting either. I didn't say why I was there or anything.
