We have added one word to the End User License Agreement (EULA), but it is an important word. The EULA can be found at

We added the word "written" to this sentence:
"You may use this software on a computer system only if you own the system or have the written permission of the owner."
We felt that this was an important addition in order to avoid any confusion. There have been a few situations where donors felt that they had permission, but the owners of the computers did not. Having written permission is the best way to make sure that there is no doubt. It also gives protection to the donor in that he/she would then have proof of permission, avoiding problems involving oral agreements.
