I think a fan-film should have both a website, and a teaser available before it's included. (audio too). That at least proves a modicum of dedication on the projects part.
Ideally it should also have a preview which requires at least a start to filming. IMHO there are just a ton of projects that start out with the best intentions but go nowhere, or are so many years from even filming that they just won't be of sufficient interest to people who are browsing these forums for a Trek fix *now*.
There's my 2 cents which is currently worth about half of Hudson's 2 pence. ;-)
