How do i add people to memory maker

Anyone already listed on your account will be able to add the photos to your MM via their MB. If they are not currently listed in your friends and family list (ie they have their own MDE) then you need to add them as a friend and family by sending an email invitation thru the MDE account. The MM is only assigned to one single account. The account that owns the MM is the account where edits and downloads need to be done.
