This is awesome.
I'd also like to mention that a number of the NT members (including those who didn't compete at Jr. Nats) supported the course review hosted online by the Youth Development Program this past Saturday. It was pretty amazing - the last participants signed off at nearly 10:30 eastern time, after 3.5 hours together!
I hope youth will seek out YDP as a way to connect with other youth, including NT members. This year, we'll be offering YDP resources to all the youth NT members because that's where OUSA's development effort is focused, including being part of the invitations to socialize, train together, participate in course reviews, and apply for grants for youth-focused activities. We're working to develop a structure to support the youth mentorship interaction you describe.
I like the model course / warmup idea. Perhaps we'll try that at a future NRE as our during-event activity.
