Cloudflare would be a solution for activating HTTPS on the main Github Pages site for free. Github Pages would work out of the box, since Github already has a certificate. The forum and other subdomains would need a SSL certificate, or then we could use Flexible SSL instead of full SSL. http://cloudflare.com
I could setup Cloudflare for the cuberite.org domain and give the Cloudflare login details to e.g. xoft.
