Ok, I checked all four email addresses you mentioned earlier, plus the one you mentioned in your last message. Here's what I found (listed in the same order that you gave me the email addresses):
[email redacted] - His subscription is pending. In other words, he subscribed to receive updates via email but he hasn't confirmed his subscription (by clicking the confirmation link in the email he received about his subscription). If he hasn't received that confirmation email, he may need to check his email's Junk/Spam folder to see if it ended up there.
[email redacted] - Her subscription is also pending (same as above).
[email redacted] - This email address isn't subscribed. She'll need to sign up to follow the blog at this email address in order to get email updates.
[email redacted] - Her subscription is also pending (same situation as above).
And the email address you gave in your last message: [email redacted] - Her subscription is pending (same situation as above).
Please let me know if I can do anything more to help with that. :)
