BBSlink was created in early 2014 to allow sysops to easily add door games to their BBS. Other InterBBS door servers existed, but either have extremely complicated set up procedures, or are unnecessarily selective about the BBSes they accept.
BBSlink was created with the following principles:
Free to use for all SysOps
No selection criteria – just running a compatible BBS
Simple to install for SysOps
Seamless connectivity – no splash screens or compulsory menus before entering the door game
