Alr, so I see people with labels on their names. What do they mean? One is an Ambassador, another is a Senior Moderator, and there's one called the Wizard. So what are they for? (And sorry for putting this question under Miscellaneous; I didn't see anything about the type of question I was asking.)

Ambassadors, moderators, and senior mods are all staff here to protect the site and ensure everyone follows the rules. Other “labels” Im greens are titles you can get for obtaining medals for specific subjects, to get medals you need to answer a question someone has and if you receive a medal you get a coin, when you get enough you can purchase a title.

As for titles such as the "Wizard", those are earned via SmartScore; as you reach a different level in each of the three sub-categories, your title might change. 
"Hatchling", "Neophyte" are examples of the lower titles, but you'll earn more along the way. It's fun to figure out :)
