When asking a question here on Meta SE, the sidebar titled "Step 1: Draft your question" (which appears as a dropdown menu on mobile in the responsive design) has the following text:
Is your question about the Stack Exchange engine that powers the Stack Exchange network?
The hyperlink on "network" points to http://stackexchange.com/sites
. Can this be changed to use HTTPS?
More generally, it seems (after checking on a bunch of Meta sites including Meta Stack Overflow) that the hyperlink on "SE parent site" in
Is your question about the [SE parent site] community or website?
always points to the HTTP version of the main site. It would be great if these could all be converted to HTTPS.
