Yep Emily is young but you'd never guess it, she's really smart and mature - i'd trust her with my herps any day!
Madhatter and RachelS also come to mind, they are really cool and great to talk to. They all put lots of forethought into an animal before getting it.
I too am young (17), and I read every single caresheet online and ask all the questions I can before going ahead with something. I know the people on here have lots of experience and KNOW what they are talking about (for the most part), so I LISTEN to everything they say!
