I went to follow a bookmark to the site this morning, and I got a certificate error:

www.designers-guide.org uses an invalid security certificate.
The certificate is only valid for designers-guide.org
Error code: SSL_ERROR_BAD_CERT_DOMAIN

I took the "www." off the front and got here. That was with Firefox on Linux.

I also tried Chrome on Windows:
