When people leave a comment on your blog post, typically they receive a message that the comment is awaiting moderation.

This means you need to watch your blog dashboard, in order to approve pending comments.

Check your blog for pending comments, especially at the start of each week, since your classmates are expected to comment by the Monday after each new post.

If you have questions about this moderating, ask a classmate or me, or some other knowledgeable source.  Thank you on behalf of responsive readers everywhere.
