About a year ago, a shopper reported that Yahoo was directing some of her email to Trash. Check your Trash folder for any surprises. Since it's been a couple of months without a reply from Nancy, maybe she is gone. But, if she's still there, and communicative, you could try copying her email address from the ACL site, paste it, and send her an email, asking her to reply back. Then, just wait and watch your Inbox. You could try that with any other ACL editor whose email is not reaching you.
Hope you get this figured out.
