From the Traveller RPG Wiki on wikia.com:
Joe Fugate was one of the founders of Digest Group Publications. In 1986, GDW used the growing writing talents of DGP -- with Joe Fugate as lead developer -- to produce MegaTraveller. In addition to writing and editing books for GDW, DGP continued to produce additional material for MegaTraveller under their own imprint.
After Joe Fugate sold DGP to Roger Sanger, he left the RPG publishing world. He now works as a software engineer, web site designer, and on model trains.
