On my Profile page, it appears that I have the option to put in a video link. I wanted to link to a short animated feature that I made last year, but am having no success. Any clues as to what I might be doing wrong? It works with neither youtube or vimeo, are these prohibited sites?
Thanks!

I think there was some sort of programming disallowing the embedding of videos. Your best bet for now is to put a regular link to it, perhaps with an image-still from your work.
