I joined letterboxd !
Here's the link, feel free to follow me, if you are already there.
Letterboxd is a social network for sharing your taste in film. A movie journal of what you watched, rated, and (if you want) reviewed. I think you can only join, if someone sends you an invite. A fellow LAMB invited me, and I see many others from LAMB community have accounts at letterboxd. However, anyone can surf the site for reviews, lists and ratings, even if you don't have a profile.
Happy "letterboxing" :)
