Additional Notes:
Mark Hatle says "There were two versions of TPro both written by Guy T. Rice. (Do a google search and you can find him around still.. he's works for a company in St. Cloud MN now.)

The "older" version reminded me of a "standard" BBS.. not really based on anything, it has T-files, file transfers, etc.. (but I had limited experience with it.)

The "newer" version of TPro was based on all new code and the message system looked like the older TPro as well as Citidel (or Pseudodel). It has rudementry message networking, and I even wrote a (read-only) usenet gateway based off of a VAX connection a friend had at a local university."
