VOTW (video of the week) weekly winner receives a button in their postbit?
 

I run HaloBoards.com and we do video of the week contests where people submit a video for a particular category in the week.

What I'd like to do is set it up so that the winner of a poll in a specific forum automatically is given a small image in their post bit that says something to the effect of "VOTW Winner"

Is this possible? Has it been done?

It would also have to allow for repeat winners (and it'd be great to have the date show up as the alt text when hovering over the image). Anyone try something like this before? Or am I looking at a paid modifcation request?

Any help perhaps?

this would be a great mod. I am with yeh
