The basic mechanics of the site are that you get a choice between two films. At that point you can do one of the following things:
- Vote for one movie or the other
- Say that you haven't seen one or the other
- Say that you haven't seen either
I have been a member for a day or so and I already have a list of 420 movies and have done 1,369 rankings. The site is really interesting and is a fun time-waster. I highly recommend it.
Here is my profile page if you'd like to see my list.
