[Request] Limited amount of threads viewable by guests.

[Kikkerking]

Hey there.

I'd like a plugin that makes guests only be able to view a limited amount of threads, and that you can set how much they can view in an option. What I mean is, that the guests can view 10 threads, and after they try to view an 11th, they will get a message saying eg. You've reached your limit for viewable threads for guests. Please sign up now for full access!

I hope this can be done, thanks in advance.
