One subject that has recently come into play on the Khan Academy WIki is the subject of underage individuals.
User:Raumaankidwai, and User:Seonghyeon got banned for it, so I wanted to speak of how we feel at this wiki about this subject.
As far as I am concerned, babies can join this wiki. As long as they don't do something overly immature, I am fine with it. I am sure User:EytukanStudios is fine with it as well.
But, just so everyone knows, ages are still not to be discussed on this wiki. Mentioning ages can lead to a kick, or a 2-hour ban to a three day ban, depending on how you present it. Keep in mind the Wikia Terms of Service does mention this explicitly.
