Does this mean that I can use one of the licenses I have to develop a site on an address such as http://dev.domainname.com/ and then (once development is finished) when I assign the real license (a new one) to http://www.domainname.com I can reset the license for the development site to develop the next one? This will be a wonderful feature if so, and one I am desperately in need of. Is there a limit to the number or resets that can be performed?
Yup! That's exactly what it means! Merry Christmas..... no limits that I have heard of, and would be kinda dumb anyway - but a fair question. If I find otherwise I'll advise you here or in a new blog post! Have fun with it.
