I started getting spam comments, that were sometimes a bit embarrassing, so I now moderate the comments.  They are emailed to me, but then I’m required to login and publish them.  If you notice that your comment hasn’t been published it is simply laziness on my part.  Once I have had the pleasure of reading the comments in my email,(I DO enjoy them!) I tend to forget about them.  So, I apologize, and don’t take it personally if it hasn’t shown up.
