On the forum here, TLS isn’t even available at all. Some study showed that over 50% of people reuse login passwords… :-/
I guess you do know how easy it is nowadays to encrypt your website…?
languagetool.org is only available via HTTPS, how did you manage to open the page with HTTP? Requests to HTTP are supposed to be redirected to HTTPS automatically.
The forum isn’t available via HTTPS because the hosting company offers it only in a package that’s too expensive for us (Discourse Hosting Plans and Pricing - Communiteq).
