http://forums.psychcentral.com/forumdisplay.php?f=76 and see who is active/discussing the subject of interest to you; it could be they have the same acronym (I don't know why they do, I agree with you) in the listing because a new person might not be as savvy as you as to their having different acronyms and be confused like some do with Bipolar (BD) and Borderline Personality (BPD) disorders?
