According to the one announcement I could find, GS-Point is a package that allows an Atari ST to act as a FidoNet Point and recieve and send network mail and echomail. This is not technically a BBS, but GSPOINT sometimes shows up cited in Fidonet News as a way to recieve Fidonet. Development was done by one "Fidgit Greylock" of "Greylock Software".
