Yes but when I wave the mouse over the star is say 25 and 25 for the green stars. The other stars in other colors are for more from what I can tell. I think I am still a new user until I have been here for a certain amount of time though. See, my first star (green) came after I made 25 posts and then another one came when I hit 50 posts. So I think that is what the green ones are for.
