Letterboxd
I have three invites for Letterboxd so if you're interested, just leave your email in the comments.
From the website: Letterboxd is a social site for sharing your taste in film. Use it as a diary to record your opinion about films as you watch them, or just to keep track of films you’ve seen some time in the past. Rate, review and tag films as you add them. Find and follow your friends, to see what they’re enjoying. Make lists about any aspect of film you like, for example: favorite heist films.
