T.A.G. was written in Borland Pascal and is free for business or personal use. The authors considered it fun to give the program away while others tried to charge for BBS programs.  The software was a fork from an early version of the WWIV source code. 
Peak number of running systems: Just over 1000, mostly in the United States and Canada. The largest concentration was in the Detroit area, where it was one of most popular BBS software run in the area. There was a somewhat friendly rivalry with the Telegard team, which also started in the same area.
Areas of major T.A.G. BBS concentrations:
- Michigan: Detroit (where it started), Lansing, Flint and Battle Creek
- California: Oakland
- Connecticut: Hartford
- Florida: Jacksonville and Cocoa
- Maryland: Baltimore
- New Jersey: Newark
- New York: Syracuse
- North Carolina: Raleigh
- Ontario, Canada: Windsor and Hamilton
- Pennsylvania: Pittsburgh
- Texas: Houston, Beaumont and Fort Worth
- Virginia: Norfolk
A quote from one of the authors:
- We all poured countless hours into the development and support of people running BBSs. Even today I don't think the internet has come close to the sense of community and simple accomplishment that BBSing provided. Building and running a complete environment on your local computer and watching people use it is a far different experience than putting up a web page on some remote server. We all made and still have a great many friends from being sysops and BBS developers.
- No one ever got them to answer definitively on what their name stood for, but there was a reasonably reliable rumor that it was from "The Adventurer's Guild" which was a Dungeons and Dragons sort of reference.
The only known T.A.G. BBS still in existence can be accessed via telnet at diskbox.homeip.net
