Alert moderator when a new comment is posted. It re-enables a feature of the first WordPress versions that then behaved erratically.
WP NotifyComment is a very simple single pluggable function plugin with no widget interface. A mail is sent to the moderator when a new comment is posted, to alert him that moderation is awaited. This function was originally working on the first WordPress versions and then has behaved erratically after a change in code (malformed header).
