The first fanmade website I came across on the net was created by Zorina Skye. The site was gone shortly after I discovered it... however, it quickly returned to former GeoCities.

Besides Greg Chin's FAQ it contained fan-fiction and an episode guide of SRaTSS. Zorina was also the founder of the Saber Rider and The Star Sheriffs Webring. Nowadays the webring is virtually abandoned. Anyway, Zorina's site used to be online for years but the last time I went there it was suddenly gone. Below is a link to the Internet Archive Wayback Machine to access Zorina's former site...
