I was able to add my new email address as a Linked Email Address but the default email address is going to be deleted. So, here I am. Looking forward to help. Sending to either the Yahoo or PM account is fine. Thank you!
PS. I spent an hour trying! There is no Admin Console in Account for me to click. Changing the email address in Profile, even adding a company name, says the name is invalid. Trying to open a request ultimately failed Other posts have had responses stating an email was sent, from support, to change their email address.
