 From 1988 on, PCBoard systems were able to host similar functionality known as RelayNet, while other popular networks included RBBSNet from the Commodore 64 world, and AlterNet.Late in the evolution of the FidoNet system, there was a proposal to allow mail (but not forum messages) from these systems to switch into the FidoNet structure.This was not adopted, and the rapid rise of the internet made this superfluous as these networks rapidly added internet exchange, which acted as a lingua franca.
