Caroline,
 
Thanks for the response.  The very first time I signed up, the spam filter on the email server caught the confirmation.  However, I white-listed it, so everything should have been good to go.  Or so I thought.  Was the message you referenced from my most recent sign-up? If so, that is odd.
 
I'll look into it further, but I do have another email I can use in the mean time.  Thanks clearing this up.
 
Pat
