>TeenVGN< is a platform for veggie-eating teenagers. It's completely free to become a member and chat with other young people who's vegan or vegetarian (I'm assuming they mean vegetarians that eat dairy and eggs).
TeenVGN is a nonprofit organization dedicaded to help young vegans & vegetarians with recipes, activities (like summer camp!) and inspiration. They also have a >Youtube channel< which seems to be updated at least every two months.
