My Graffiti Wall mod for vB3 users

I've posted my Graffiti Wall for vB3 users on vbulletin.org; if you aren't running vB3, I have a standalone script you can download from MPDev.Net.

The Graffiti Wall is a simple script where people can "paint" text onto a brick wall. You can see an example of the vB3 integration on ExtremeFitness.Com.

I also use an img src with half sized dimensions to preview the wall on my Summary page which can be seen on ViperAlley.Com; this could also be added to your portal pages for greater exposure.
