What about /wiki/Installer -> /wiki/Windows for better SEO?
Eventually we should also mention /wiki/Windows on /wiki/Download as well as /wiki/VirtualBox and /Download. Exciting Whonix times for platform support!
I am very much for you signing them.
(Until we maybe some day get something better than signing by individuals. Signing by a somehow securely shared project signing key and a build server and deterministic builds. Could be years.)
Generally, not all in Whonix development activity can be proxyied through me. I'd like that, but time and energy has physical limits unfortunately. I am glad that there are other maintainers taking responsibility for other certain components.
