I've used a RT template for a customer's site. The project is finally online, and my "commercial relationship" with my customer has ended... but now he's concerned about his template's licensing.
The point is that I'm the "owner" of his entitlement, but as I said our relationship has ended, and he doesn't want to have any legal problem with his site. How does it work? Does he need to have any documentation to prove that his entitlement was provided by me?
