I don't know for certain what you mean by renting a license. But if you are talking about letting another person pay you for making use of your license for work in which you will not be personally involved, then I suspect that that is illegal. So for the moment, at least, I will be closing this thread. If you wish to explain your intent in a private message to me, I will share your explanation with the other moderators, and we will decide whether or not to reopen this thread.
