Some (or all) of you may know this, but I wanted to shre this awesome video sharing site with you. It is geared toward film makers and it allows free upload of HD files.
The moderators do a good job of responding quickly to your concerns or problems. They've been doing a good job of preventing the site from turning into YouTube. Check it out. There are some good short films on the site and the cool thing is... you get constructive criticism about your work from your peers... whether it's about the editing, the composition, the story, etc... You can learn a lot.
