The past few times I've accessed the site, I've read the following in both my login field and the password field: "This connection is not secure. Logins entered here could be compromised. Learn More." Is this a known problem, and is it being worked on?
Not a problem, as such. This site doesn't have the newer security protocol ("https") and some browsers, including Firefox recently, have taken to warning their users when they use a site that requires a password but has the less secure "http" protocol.
