If your browser has been throwing security warnings or errors when you try to access the web server at febo.com (for example, the list archives), that problem should now be fixed. I was using an SSL certificate issued by StartSSL, a company that has sort of shot themselves in the foot due to their ownership structure and lack of transparency. A few months ago the major browser vendors have stopped recognizing certs issued by StartSSL, and their browsers now give warnings when they encounter a StartSSL cert. There's no evidence that my certificate was vulnerable or was ever compromised, but I've now changed over to certificates from a widely-supported group called LetsEncrypt, and you shouldn't see any further security warnings. Thanks, John
