The licenses are issued to the company (if the company name specified in the order), so they are not bound to any individual name.

One thing to do is unlink the license ticket from the user record if this user leaves the company. If the user (or we) don't do this, then new user will not be able to link the license ticket to his user's record and so he won't be able to access the license information via My Control Center section of the EldoS web site.
