I read in the rules of the forum that when I sell a product key I need to prove my ownership. Well I bought a key for Microsoft Office 2011 from a website and they accidentally sent me 2 keys. I would like to sell this second key, but how do I prove my ownership? I know that the keys are legit because the first one they sent worked. They emailed me the codes.
thanks in advance,
