vBulletin had two add-ons / mods for this that I've used.
I'm using iShop over at MysteryDistrict.com (Demo Thread: http://www.themysterydistrict.com/g...tery-icon-shop-use-your-district-dollars.html) and WaltDisneyBoards.com (Demo Thread: http://www.waltdisneyboards.com/new...n-prepped-feature-new-projection-effects.html)
I'd love to have an option for xenForo. Anyone else like this idea? If so, please click "Like" for this thread and post. Let's get some interest generated
