The mystery explained...
MB is saying HM which stands for Howie Meeker, an infamous former poster, (now banned), who is very disgruntled.
If it is him, he would have to be a real dumb ass to keep coming back here under different handles, when he claims to hate perb and claims to want nothing to do with it/us. I don't think Bull is HM but Maury may know something I don't?
