Having difficulty getting to the website? Try using https://chilternhundred.drsolly.com/ and https://chilternhundred.drsolly.com/bonus.cgi rather than the web addresses listed in the description (which include a “www.”).

The SSL certificate presented by the web server covers “*.drsolly.com” which modern browsers to not interpret as including “www.*.drsolly.com”, so you may get “Secure connection failed” errors otherwise. (CO might like to update the links or else expand the certificate!)
