Do I feel stupid!

I’m crushed! I have just discovered that all the vague, short comments with a web address at the end are leading to sites promoting Viagra, etc. I guess spam now comes in sincere-seeming comments. From here on all comments will be moderated. Any with real content will be allowed unless a listed web address leads to some obviously commercial, unrelated site. Also, any “comment” with no readable content will be denied. I apologize to anyone with real comments and I will do my best to approve within a day any (positive or negative) comment that relates to the topics of the site.
