I clicked the login button then immediately began entering my username and password before the background image for the page had loaded. When I hit the tab button to switch to the password field, instead of it automatically deleting the "password" prompt in the field as I began to type, I saw it post the first character of my password attached to the end of the "password" prompt in the field. I manually deleted all the characters in the "password" field, including the prompt "password." By this time the background image had loaded. I then proceeded to look down at the keyboard as I entered my password as usual. Upon finishing I looked up and saw my password exposed like a... you get the idea..., instead of the typical "******" covering up the password. I think this is an important bug to report, since it could expose a person's password if the person is logging into the community site from a public location. This is the first time this has happened to me.
