What if the emails aren’t getting through?
If you’re not receiving notification emails:
First check to make sure you are the author on the post where the comments are getting added.
Check the Settings > Discussion page to make sure email notifications are turned on.
Check the spam/junk folder in your email program to make sure the messages weren’t filed there by mistake.
If you are still having trouble, contact Staff for help at this link on on Monday, October 17th. Here’s the link http://en.support.wordpress.com/contact/ After you use the searchbox, under the search results, at the bottom of the page there will be a section that says “Have you found the answer to your question?” You can choose either “Yes I found the answer to my question.” or “No I didn’t find the answer to my question and I would like to contact support for help.” The no option will reveal the contact form.
