When I needed to update my first XF site, I downloaded the upgrade package from my XF account. It seems to have a unique id number which I presume allows you to help manage licenses and theft. When I update other XF sites, I have been using the same file rather then downloading a new one for each site. I have two questions: - for those of us who own multiple licenses, do this cause any problems for you? - I sometimes perform installation updates for others. When that happens I have been using my same update package file. Is that a problem? I would also suggest it would be helpful if you offered a tool whereby a developer could enter a website address and confirm their license is up-to-date.
