Those are two support groups that we have on the internet to provide support, education and suggestions to those who have a significant other, relative, friend, co-worker, or even a neighbor with Borderline Personality Disorder or BP traits.
People talk about the issues that they're facing or have had to face in the past.
Some folks are with their significant other and some are not. One list member keeps his dog, Yoda there when he comes to visit. About Oz is a group that we use to discuss problems that may occur with someone else on the list. It's like a den or workroom. You don't have to join both groups.
