In a similar vein, I finally got Movable Type (MT) to automagically email me when someone leaves a comment. At first, I thought I had a problem with sendmail either being in a different location or not being available at all. But all it was is I had to check a box in the configuration file for MT that enables that feature. Doh!
So now if someone leaves a comment, it gets emailed to me rather than me having to check the site periodically during the day.
