I was scrolling through community central, because I look at what other people are doing for their wiki and I do the same, and I found you, so that's cool. I'm not sure, but I think it is like achievements- you have to email the fandom staff and they will apply it (Since it is still new/Beta). Or it's something in the CSS. It's one of those 2
Edit: The other guy gave the response as I was writing so you don't need me
