Here's a list of all sorts of things related to youth rights. It's not a list of ideas we endorse; our only official stance is on the voting age. Neither do these people and groups necessarily endorse us. However, if you're interested in Voting Youth, you'll probably like a lot of the stuff on this list.
If you know something that could be added, send an email to general@votingyouth.org.
