I am so excited that Anne and Helen have left a comment on my welcome post.
It is an interesting process when a comment is left. I have total control of all comments.

• An email was sent to me with a links to:
  • accept the comment
  • delete the comment
  • mark the comment as span

I, of course, accepted them.
If you are thinking of using blogs in your course, know that you can review comments before they are posted as can your students if they have blogs.
