Thanks for the heads up. I was thinking it was allowed although not really a kosher thing. I will try to go through all of my games I currently have up and edit them (I won't have time to do it tonight though but later). If it helps it's not like a normal ref link -- it doesn't give me anymore luck than anyone else in the giveaway in the form of an extra entry. It's simply to keep track of friends who sign up to the site.
