Flixter
My friend Lori has invited me to Flickster. Very fun. I could waste a lot of time there. I’ll try not to do so.
(Note added March 28: I would advise against using their tools to invite your friends. That’s just really bad netiquette, for one thing, and there are other security problems and issues as well. Get the url of your flixter page and send that, via your own email, to your friends.)
