The "Other Fan Projects" is meant to cover projects such as de-specializing efforts, fan-made documentaries and miscellaneous stuff like split-screen DVDs. I've never been 100% happy with the forum titles and descriptions, so feel free to come up with some suitable text.
The fan edit discussion forum comes first because back in 2007, after the petition had fulfilled its purpose, that's the way the site looked to be heading (check out Jay's 2007 news item on the front page). I agree that the focus has now shifted back to the originals, although adywan brings in a lot of traffic to the fan edit forum. I'm not sure if the listing order is particularly significant, and with people being used to the current order, there is potential cause of confusion if they are moved around now.
The forum for fan edits of films other than Star Wars is relatively quieter these days, probably because of fanedit.org.
