Leagueman

Assume you have a community site with a large user base. Dont you or your users want to know, which is the most popular team? Which team has got most of the fans?

You can see the result of such a simple fan counter in the popular teams module on this site. You can also see the count of fans on the history tab of the teaminfo page.
Now I am looking for a place where a user can select his favourite team. Whether or not he can select for every project? Or only once he can select his favourite club?
