I haven't seen her around. Maybe she is on the Facebook group with TPLaw? A bunch of the good people got tired of all the shenanigans at TS and pretty much abandoned the place and started getting together on Facebook. I wasn't on Facebook or I probably would have joined them back then.
I know TPLaw signed up here at the beginning, but I don't think she has ever posted. You could send her a PM though and ask if she knows where to find HBG. The PM should trigger a notification to go to the e-mail account she used to register here.
SC I liked both of them but am not sure that they were friends. Taz should know. Really.
You're right about Taz, he knows just about everybody. He comes by a couple of times a day usually, so you probably won't have to wait long.
