I'm sure I don't know Frobisher/Doc, I vaguely remember someone by that name on PF. This isn't a sub-forum - DP is a Forum just like PF - which I left because the mods there were unbearably right-wing leaning and though they didn't ever ban me, they kept deleting my posts for no reason. They couldn't stand when someone stood up to their "faves". Sort of like they did with you. I haven't been to PF in quite a while, so I don't know about the post you are talking about.
