I’m in the middle of migrating this website to new servers this week. This means you might encounter some unexpected behavior until I get all the bugs worked out. Clicking on my links (including this one) might cause your browser to give you the message that it’s a site without a current security certificate. It’s not actually unsafe, but there’s something which isn’t yet set up for the security certificate. I apologize for any such errors you might encounter while the process is going on. If you notice any problems with content which didn’t migrate properly, I would appreciate you letting me know the details at davidmcelroy@mac.com. Thanks for your patience.
