Just a note that I'm happy to enquire for anybody who hasn't received an email, however, sometimes the answer will be that there is no explanation of why you haven't received it. Efforts are made by email providers to limit the amount of spam that you receive, and sometimes they decide incorrectly that emails from contact lists such as ours are spam and block them even before they get to your computer. If this is the case then, typically, all we will be able to tell you is that the email was sent.
