Yes, send a PM to an assistant administrator; either me or
jurupamae or
CK, and we can sort things out for you.
You can either provide an alternate email address for your sister (there's no need to have a parent email address listed, that can just be removed), or we can alter the birth date details to yours and you can take the account over yourself as your sister hasn't used it. We'll give you a free name change if you choose the second option :yes:
