I changed the email address in my user account some time ago, but now I get newsletter to both emails!? I find no references to the old address anywhere in user control panel. Should I opt out of the old or will that cancel both (account link) ? The opt out mail link looks like it's both an account number and some other identifier.. ie they are not totally equal addresses. This is luckily only for the newsletter, I don't get every forum notification duplicate.
