It's not much of a resource for fan films, but it's the official Star Wars site:

Now Showing!! - the Clone Wars
A great resource. Message boards and discussions, primarliy a means for fan film makers to organize, share ideas, promote their films, etc.
Read the sticky at the top of the page that starts "Read this before posting.."
And, you can offer suggestions and comments about my site on the discussion thread in the TFN Forums:
This is Adam Bertocci's site (a fan film maker). It includes Adam's films as well as reviews of other fan films. The link here is to the reviews page:
A teriffic site for Star Wars fans. Tons of great content here, and they just happen to have a good download page. After TFN, this is my next-best resource for download links.
Yet another crucial resource. They have far more than just Star Wars films listed on the site. This is not a download site, but more of a locator and listing resource.
Considering that AtomFilms gives out the official Star Wars fan film award each year, there will be some people that will think it's odd that this wasn't the first link at the top of the page. The reason for me is simple: AtomFilms is easy to find, and it's all streaming video. With the download library being the largest focus of my site, those links were first. No slight intended.
This is Clive Young's newsletter/blog for all things related to fan films. He does a great job on this site, and there's something for fans of almost any genre.
This is another site out of Poland with some good fan content (not just Star Wars). Be sure to check it out.
This is a pretty cool site, dedicated to 3D work in Sci-fi. Includes news, fan art, forum, etc.
