Force users to read thread Vbulletin 5

[mp3president]

Hi,

Can anybody help me with this?
I want to force users sometimes read threads before they can go further onto the forum.
I can't find anythig like this for Vbulletin 5.

I have this one working on VB4 :

Does anybody have something like this?
