Btw rso I find you quite ironic. First you ask me if I know of anyone else who is a tzadik gamur of Tanya, I respond no and I’d love to know of another, as there is no reason to be unique in that regard. You respond that feivel thinks his Rebbe is one, and then refuse to give his name. Do you get the irony here?
Skulener Rebbe probably qualifies.
