Several potential commentors have e-mailed me saying they have tried without success to post comments here. If you have that problem, please let me know at: [email protected]. I will not be able to respond to all e-mails, but I would like to know how many are having this problem. My blog master says the WordPress spam filter has detected a lot of spam and automatically trashes messages it thinks are spam. Sometimes that includes valid comments. I want to know how big a problem this is before I go to the blog master to see what might need to be fixed. Thank you.
