This might raise a problem. Or not. I have always used this same AOL account/screen name/whatever they call it these days, for any business involving my leather club. (Of course, it looks like the club has mostly abandoned Facebook for anything. Even the club website no longer even has a list of events. You have to go to Bluesky and maybe another platform [?] for basic information like that. It's all very confusing.)
So wait, are you saying you don't want the leather club to see the Brokie posts and vice versa? You can actually have multiple accounts. For example, I've thought Chrissi must have multiple accounts -- I'm friends with her as Penth Esilea (her Brokie name) and her posts are always in Engish, but I would imagine she has a different account, maybe with her real name, where she writes posts in German for friends in Germany. This may apply to other Eurobrokies, though not all, because I do see some posts in other languages (Facebook can instantly translate). I don't know for sure about Paul, I'm friends with Paul Southendmd on Facebook, but I would imagine he has an account where he uses his whole name for colleagues, former classmates, etc. (correct me if I'm wrong, Paul).
So you could have Jeff Wrangler for one account and maybe Leather Jeff or Jeff W. or whatever for another. Or you could just use your whole name (I seem to recall you used your last name on IMDB) but let people know that's who you are. There are Brokie Facebook groups (Amanda and I started one, Bluebirds & Whiskey Springs) where you could do that.
