Thanks for asking Tara, and of course welcome at Dominion Online!
What could have gone wrong?
1) Have you checked SPAM and/or Junk folders for the email?
2) I've seen confirmation mails take 12h to reach me, when apparently some intermediate problem existed that delayed the mails. Maybe wait 24h after registration.
3) Are you sure you did not mistype the email address? Though unlikely, it can happen.
What can you do?
If you suspect 3), you can just resubmit the email address (just as if it had changed) from your "Account" tab. If it's nothing of the above, you can contact me again via private message and you can give me your account name and I can manually confirm your email address. It's not the preferred method, as this is the email address that we send you any "password forgotten" links to. If there is a problem with our emails reaching that email address, its better we figure it out now than instead when its urgently needed.
