SpaceQuest.net, run by Frans, is the largest active Space Quest fansite on the net. It contains information on each of the games, both from the SQ FAQ, as well as Frans' observations, and of course downloads (demos, manuals, patches, box covers etc). The site is the home of Janitorial Times, a message board for the SQ community. More information about this website can be found here.
The site has in the past hosted Space Quest Community News, an operation that Frans began, trying to link the news pages of the various Space Quest-related sites to one another. The operation ultimately failed due to lack of interest from the outside community, and was discontinued by Frans.
