RelayNet was similar to FidoNet in purpose and technology, although it used names for its nodes instead of Fido's numeric address pairs.
[3] PCBoard, created by Clark Development Corporation (CDC) in Salt Lake City, Utah, was always a "premium" BBS system and fairly expensive.
For this reason it was limited mostly to larger multi-line BBS systems, where it was particularly well liked due to its "nice" behaviour on the network when running off a common file server.
RelayNet software later appeared for a variety of other BBS systems, including RBBS, GAP, EIS, QBBS and Wildcat!
BBS, but these systems also provided excellent FidoNet support and RelayNet was never popular on anything other than PCBoard and its close competitor, RBBS-PC.
