Request Connection without seeing Profile

I am building a site that needs a good amount of security and blocking. By default I only want users to be able to see other profiles that they have an established connection with. The only way I have found to actually request a connection with someone is by going to their profile. The problem is that I don't want them to be able to see the other person's profile until they have been approved to. Maybe this is something that can be done with the privacy plugin, but I'm not sure. Can you give me some advice on this?

I'd say you could make most, if not all, fields of the profile visible to connections only. To do this by default you'd probably need to make use of the incubator queries plugin right when your users sign up.

Maybe anyone who's done something like this before can chime in

Edit: there's probably a way to create a delimiter field, viewable in a userlist, which will initiate the connection process .. ?

The add connection link is just an HTML link, but adding it self where you of course will not get the JS pop-up to send the usage a message with the connection request or anything of the sorts. Please search as link has been provided numerous times.

However, the issue comes with protecting an entire profile. There's nothing as far as I am aware that can do this. You can use CB Privacy, but this is user by user privacy controls as in User A could require someone to be a connection to see Tab B, but maybe only require them to be registered to see Tab A. Of course this would be entirely different based off how User B configures their privacy.
