I currently have a Gmail account that is associated with many other Google products such as Google+ and YouTube. My email address currently contains my last name and as I am not getting married I want to change it to reflect my new name.
From another question posted on this forum I understand that you can forward your emails from your old account to your new one and can export/import contacts and filters from the previous account. What I am concerned with is having my Google+ and YouTube account connected to my new email address and being able to use the new address to log in to any Google products. In addition I use OpenId on several third party websites (like here!) and I want those sites to still be able to log me in.
Just to be clear I haven't created a new email account yet.
