An update on this: I've obtained an SSL cert for VGMdb. Although I went with DigiCert for now rather than Let's Encrypt. (I specifically avoided anything Symantec / VeriSign / etc due to
this).
I had to fix a lot of places in the code that hardcoded the protocol, so please test out the HTTPS site and let me know if there's any bad redirects, insecure mixed content links and so on.
