1. I will see if that can be arranged. Parenthetically, "q.com" no longer exists either - it is now "Century Link", and that further complicates things. I hold little expectation for that. When I was able to get someone on the phone, they said the account would have been deleted ("removed from the server" was the way they phrased it) - after 3 months - around November to December 2011.
Obviously, people can lose email accounts and attempting to use the email to demonstrate that is quite possibly an exercise in futility.
This is about people, not email.
What other options demonstrate ownership besides trying to retrieve a no longer existent email account? How about:
a.) I have all of the images that have been posted on the blog and I can send you a copy to review. If you send me an email, (at the address associated with this new account) I will send a copy.
b.) You might try whois on the actual domain name registered with Go Daddy.
c.) You might check your information regarding the blog being associated with the domain name.
2. I would love to have been able to "keep it safe", however, the ISP was cancelled by a family member. (I was a secondary email user, the service belonged to my mother, who had the stroke and the service was subsequently cancelled.) I was given no prior notice that it would be cancelled, and was not informed that my email would also be affected.
3. No, I did not find anything regarding the domain name being associated with the blog for that year between Sept 2010 and Sept 2011.
Thanks for your understanding and help.
