I'd just like to point out that the casual user isn't likely to go through every single episode he/she has seen just to add their name to the list. That would be a fairly long and tedious process. :r

Cool idea, and I'm certainly not criticizing. I'm just pointing out that lazy/busy people like me might stunt the growth of the lists. :)
