Back in the 919 BBS scene, TAG was a dominant force. the TAG BBS software was popular and used by many of the popular BBSes of the day, the main one that comes to mind is The Serpent’s Twist (Steve Dimoff). There were others such as The LinkWay BBS (David Leblond) and others whose names escape me.
There was a popular local echomail network called Raleigh Area TAG, or abbreviated as RAT. The TAG boards used Binkleyterm.
This post is mainly a placeholder so that I can do some more research and post more about this topic. Hopefully I can find some RAT files / data, as I don’t see anything online from a google search right now.
