We offer Fantasy Football every Fall semester but we only do registration through IMLeagues. We use Yahoo Fantasy Football to run our league and simply send everyone who registers through IMLeagues a link to sign up in our specific Liberty Intramural Sports league at Yahoo. We usually have 2 separate 10-12 team leagues each Fall. It's not perfect but it has worked for us the past few years. From today's email from IMLeagues it looks like they are starting to implement Fantasy style games into their portfolio so it will be interesting if in the future we will be able to do the entire league through the IMLeagues site. Hope this helps!
