Is there a specific reason for which SSL/TLS is not implemented on these forums? I am not comfortable with the fact that my login credentials are transmitted in plaintext.
There is no special reason and I agree with you that we shall add this. I'am working on a relaunch of the website anyway and I will add ssl too.
I just posted a HOW-TO that may be of use when you get around to the implementation, Till: Implementing Perfect Forward Secrecy in NGINX Web-Server This should earn www.howtoforge.com a perfect A+ at https://www.ssllabs.com/ssltest/analyze.html .
