NOTE: This is my first update in seven years, and I don't think they're going to be a whole lot more frequent than that. For up-to-date information on Star Trek fan productions, refer to Barb Reader's Star Trek Reviewed. Barb has been fan filmdom's leading detective for several years now, tracking down lost fan films and logging them on her site on a near-daily basis. When this list updates again, STR is the first place I'll check, and her information was invaluable in getting this update released.

(NOTE: Received a famous Cease & Desist order in 2004. After agreeing to certain terms guaranteeing that nobody in the production would make money, the C&D was rescinded, paving the way for modern fan films.)

(NOTE: This long-running series is very, very hard to keep track of, as it has no official website or sane episode listing. Runtime estimate is very approximate, and URL points to Barb Reader's entry for it. Barb likes the show's recent work, which means it's worth a try.)
