Taz,
In a meeting some people may say "my qualifier" and that is just a way for the anoner to maintain privacy and sometimes anonymity too...maybe they don't want to reveal that their qualifier is a son, husband, boss....etc.
I would have to say that I am my own qualifier...I don't need somebody else to qualify as an codie! Qualifiers are easy to find- people, places and things are everywhere. So for me to say A for Alcoholic or Addict here...it's just an fyi thing to explain my situation properly. Personally I still find some of the acronyms terribly confusing!
Good question and I'm glad you brought it up!
