Lol, so you'd become something even if you don't know what it is?

Anyway, a kidstaff is a sort of ministaff on this site that makes tutorials that are usually found in the 'featured tutorials' section.

To become one you have to make three 'high quality' tutorials (you're teaching others how to draw after all, and should have some skill). After you've done that you add your name to the following forum post:

Good luck!
