I am webmaster for many sites and have a both a Business License and a Personal license. The Personal license was mistakenly registered to my husband's email address (I run his company's website) but I have since updated it to one of my email addresses. I was wondering if it's possible for me to combine all of these licenses into one account for me to keep track of and then also pay the difference to upgrade to a Developer's License? Would that be possible? What would the cost be for doing that?
