I didn't get that warning, either. But it is reported as Not Secure up where the padlock would show. Do you use Windows Defender as your antivirus? Maybe that's why. Sites that don't use SSL certificates are being reported as unsafe. Since there is not a payment checkout, no financial info can be taken. But it's still unsafe. A possibility that a hacker could load malicious code onto the pages. it is a very old site. I downloaded a bunch of stuff from that site years ago.
