Does this exist?

Hi,

I was just wondering if a hack/mod is available for vBulletin which will place an importent message in a box above my forums (like if you change you email address in the members area of vBulletin, and when you come to these forums it shows you as unlicenced untill you update you email here) which is dependent on a certain post being read in the forums, and could possibly restrict users posting in certain forums untill the post has been read.

I have also posted this over at vBulletin.com but it can't hurt to ask here to

Thanks for any help.
