Sorry, I cannot view the site right now, because it is blocked. But, I was wondering how you combine several users' lists. For example, say there are action movies labeled A,B, ..., Z. Suppose 3 users have ranked action movies. Their lists are A-B-C-D-E, Z-A-B-C-D, and F-A-B-C-D. How do you combine those 3 lists to form a master list? I've looked into this before and was just curious what method you decided to use and why.
