Hi,
I'd really like to see mobileread made available over https. This is particularly important since it is used to distribute code that runs on users systems (sigil and calibre plugins).
Thanks to the Let's Encrypt intiative HTTPS certificates are now free and automated.
https://letsencrypt.org/
I recently (in the last 6 months) enabled Let's Encrypt on the calibre websites and it was pretty painless, so I can recommend it.
Thanks.
P. S. I am happy to help with any technical issues, if needed.
