The private forum is a place where the discussions often degenerate into contentious arguments. If what you are looking for is a knowledgeable OO with whom to discuss the OO Church and her beliefs, then your best bet is to have a private e-mail converstation with Fr. Peter.
If you want to have access to the private forum, though, then you can pm Fr. George and ask him for admission. PeterTheAleut, like myself, does not have the ability to let you in.
