Well, unfortunately when you started talking about it, not only do people not understand what it is and therefore not know it, but the people who originally knew about it forget.
I wish when you push the "More" button for the smilies and emotes at the right, they would ACTUALLY GIVE YOU MORE SMILIES AND EMOTES!!!!!!!! (And I mean more than just 2, cuz they do give you 2 others, but I want MOAR!)
