I am just curious. I have blue as my font color. Several classmates have inquired... what does the lighter font mean on our Classmate profile page? When I log in... there are various classmates that are in a lighter shade of blue. When I view my statistics... it doesn't correlate as to who has logged in within the past 24 hours.

Are you talking about the link color of some of your classmates? (assuming using Internet Explorer)

If so, that means you have clicked on the link before. Maybe not today, but sometime in the past.
