Something I don't understand with Friends only profile Privacy level...
As far as I can see, there is no way for a member to ask to be friend with the owner of such profile (profile set to Friends only).
In my humble opinion that is really bad. As already said with insistance during beta stage, the button Befriend, or a link, has to display and not only this obscure message Profile not available for view.
If the owner of a Friends only profile send a friend request (Befriend) to another member... Is that possible to reply to this invitation as the Friends only profile is not available ???
As for me, I think that the answer is no...
