eBay: Tiger 'unregistered'...?

[Damrod]

So, I was curious and had a look on eBay if there is already Tiger packages for sale up there. And on more and more there are notes attatcher stating the copy of Tiger is 'unregistered'... what exactly does that mean? Is there a forced registeration in Tiger that renders already registered copys of Tiger bought off eBay useless?

Any clearing regarding that would be nice, as I contemplate getting Tiger off eBay.

Tiger asks you to register with Apple upon completion of installation, but it's completely optional (though it will do it automatically if you have an internet connection at the time).

You can register the same copy of Tiger 1,000 times with Apple and it won't make a difference. There is no copy protection or registration scheme that will prevent Tiger from installing or working. This registration that takes place at the end of the installation is simply for Apple's demographic research, and you don't have to send the information at all.
