You can register either by using the cleverly named "Register TRON-ish" application in this folder or you can use the online registration.
To use the online registration use the "TRON-ish website" bookmark file in this folder if you're using Netscape. Otherwise just point you browser to "http://www.foxchange.com/tronish/". And then click your way to the online registration.
The registration fee is US$ 5.
When your registration has been processed you will recive an e-mail with the password to unlock the game. So it is VITAL that you fill in the e-mail field correctly.
