I have finally rolled out the use of HTTPS.
Important pages--login, forum index, homepage, live chat--now automatically redirect from HTTP to HTTPS.
Once your connection is HTTPS, it will stay for all the pages you browse thereafter.
As always, please report any errors you encounter. Provide URL(s) and any details you can. Thank you.
Since this is a security-related post, I will take the opportunity to remind and suggest that everyone regularly change their passwords. Never use the same password on two different websites, either.
