I had a "Private" password protected forum on vB. It could be seen by everyone, and stated that you needed to ask for a password to be admitted. It was for those who wanted to discuss more controversial topics, and not so heavily moderated for language, etc.
I know I can make a forum Private (viewing and posting if granted permissions only) forum - but then nobody even knows it is there to ask for permission.
What is the easiest way to show a forum is Private to everyone, yet easily allow those who ask for special permission? Is that possible?
