We recently added a new "giveaway" module to our loyalty platform, you can check it out at http://www.gearuplikeapro.com. The Gear Up site for Wis-pak brand doc, allow fans to accumulate points either from bottle caps or by performing social media activations.   A leaderboard keeps track of high scores and the site has proved very popular with doc fans.  In general, fans are able to redeem "real world" (non-virtual) prizes using their points.  The "giveaway" and "virtual" modules add support for using points to enter giveaways and sweepstakes or use them for virtual goods (downloads, exclusive content, i.e.).  You can find more about our loyalty platform here: http://news.metablocks.com/lists/559-4178971077
