Does MacRumors not use SSL?

Does MacRumors not use SSL? If it doesn't, why? My recommendation would be to start using SSL. Isn't it a huge security risk to not use SSL when you have several users sending usernames and passwords to your site at a given time? I ask because HTTPS Everywhere doesn't auto redirect this site to the https link. When I do it manually I get an error saying that FireFox can't verify that the connection is secure. If MacRumors does use SSL then I need to figure out why machine is having issues.
