Fanedit.com would just be an incredible thing. There's definitely a need for it!
Let's see... In addition to the ones noted above:
-maybe a place to put what special features are included
-a place to add how your edit differs from other edits that have been done.
-a place to link to a trailer.
-a user rating system would be VERY helpful.
Also, if there's more than one person working on the edit, would all of them have access to enter info in the blog, or would they all have seperate blogs? Maybe have a main "official" blog, with the ability to link to the personal blogs of each individual department. Then, people would be able to click and find out the progress of the writing, the music, the editing, the effects, etc individually. I know a feature like that would be extremely helpful over at our Ranch Edit thread.
Anyway, that's my 2 cents. This is all very exciting!
