While the forums run well via the https protocol, the embedded images - including the emoji and images embedded in posts - are served over http.
The effect is, that the browser issues security warnings about unsafe images on the site, and that on more strictly set up networks the images and emoji are not visible at all (e.g. an employer completely blocks "http://conceptispuzzles.com" as a "Gaming" website, https is OK).
I believe that https should be used consistently.
