Even though a number of you visit my blog on Trek RPG history, I wanted to tell everyone about the two-part article I just did on homebrewed conversions/adaptations for Trek role-playing. The first part is just background, but the second part lists and links to over a dozen fan conversions or resources for adapting Trek for other RPG systems - Savage Worlds, 3 versions of GURPS, Traveller, Risus, various d20s, Alternity and so on. No doubt many of these are the result of work from members of this board!
Some are quite old and I came across a few that exist as mentions only, the sites long gone. But for now (March 09), all the links are live and there's a lot of great work out there that continues to be done. Hope some of you find it useful or at least interesting.
