Yankee Trader was released as shareware. However, 
unlike most other shareware software, obtaining a
registration key does not unlock any gameplay 
features or add any additional functionality. All
registrations ever did for Yankee Trader was 
remove the "UNREGISTERED" text upon entering the
game as well as the "PLEASE HELP YOUR SYSOP 
REGISTER" text upon exiting the game.

This generic public key will remove the unregistered
nag messages and allow the game to run as though it 
is registered.

Create a text file in your YT directory containing 
the following three lines and save it as YT.REG:

This BBS
The Sysop
3484625551

Refer to the Registration of Yankee Trader section
of YTSYSOP.DOC for more information on how to properly
create the YT.REG file.

Enjoy!

(Note: If you're running one of the modded versions of
Yankee Trader from YT.Starflt.com, the "Registered to
This Bbs" line will appear slightly corrupted. The 
game seems to run fine nonetheless.)
