Ideas: Content visible only if you login/reply

[Maltz]

Is it possible to make an entire thread members only (or the first post of the thread)? Not logged in users will see the name of the thread, but when they click on it they get a message asking them to login.

I understand there are plenty of reasons maintaining the openness of information. But when I see there are 7 members and 200 unregistered users browsing the ORG, I see potential membership. If we can figure out some other way to increase registration...
