Hi philhobbs,
thanks for posting on the Community Forums.
Have you been able to reset your My Virgin Media account password? If not, just give me a shout and I can get that reset for you, providing we're able to clear through security via PM :).
Changing your My Virgin Media account password would indeed also change your Virgin Media (primary) email account password that's linked to that My Virgin Media profile.
Hope that helps.
Beth
