Underneath my user name, there is something that looks like an award. It looks like a pair of slippers or shoes or something. Could you please tell me what that is.

710, those are flippers under your name. The colours denote status. They are:

White = Member
Blue = Enthusiast
Bronze = Bronze Enthusiast
Silver = Silver Enthusiast
Gold = Gold Enthusiast
Platinum = Platinum Enthusiast

Once a member attains Diamond Enthusiast status, the flippers are replaced by a Diamond.

Information on how Enthusiast status is awarded can be found at the end of the Site Rules.
