Starfleet Online (SFOL) was an online message board based Star Trek role-playing club that existed on the Prodigy online service in the 1990s. During it's height, SFOL was the largest Star Trek role-playing club on the service. However, as Prodigy declined in popularity, SFOL suffered. In 1998, SFOL attempted to reconstitute itself on the internet, but was unsuccessful. It is unknown if SFOL on Prodigy was related to the similarly named Starfleet Online on America Online.
