I'm not being nosy; I'm just trying to clear things here. Cesar's userpage clearly states that he is 11 years old. I've also taken a photograph in case you try to edit it.
The wiki gets little to no activity. Just look on Special:WikiActivity on the wiki, and you'll see that the wiki is dead. The only "regular" users there are you and Cesar, and you two don't even do much on the wiki.
