Ah, the face........ Basically speaking, it is that members "social" rating. When you see a brand new member, they have a blue "lifeless" looking face. The next step up is the yellow smiley face. The next step up is smiley face with open mouth ( which is what you have ). And the very best rating is the smiley face with open mouth AND a white glove with thumb up. Now the other spectrum, the first step backwards is the angry yellow face, the face with a unibrow, then it goes down to an angry orange face and the worst rating is a red face with a helmet ( I think ). The ratings are based on the number of friends and factor in how many people have blacklisted "you", blah.....blah.....blah...... ( it's some ancient Chinese secr@t formula that admin uses ). I wouldn't get caught up in ratings, if you opt not to interact with members that don't have the happy faces, you might miss out getting to know some really wonderful members.
