My last name changed a long time ago - from Grynenko to Hamilton, but for some reason it's locked in go365 when I post a question (i.e. it still shows me as Grynenko). I'm also not able to change my user name which was automatically assigned based on my maiden name. Can you please help change them? My go365 account is under a corporate program, and I've been Hamilton for many years in all of the corporate systems aside from go365.
