Because of extreme quantities of junk comments that started crashing the website, I’ve turned off the ability to make comments unless you are logged in. No one I really wanted to hear from was making any comments anyway as far as I know (I probably wouldn’t have seen any such comments anyway as it would have been drowned in thousands and thousands of junk comments very quickly!). I may create some logins for folks I would like to be able to hear from if there’s any interest…
