It's the name you chose when you signed up. It is the name you will use when you submit reviews. In the past VIP members could also choose an unlimited number of "alias" handles for posting on teh boards, and one "alias' handle for posting reviews. With the new rules you can only choose one alias besides your main handle. (if you are VIP--basic members don't get an alias) You can onlyu use the PM system with your "real" handle.
