I am definitely joining in! I livestream constantly for Wounded Warriors Project, and this would be just as fun and fulfilling. And I'd love to help build or manage plugins It's my thing Hope that we get over 1000+ people streaming and most importantly; make the money for the kids in need!
Dude, don't be nervous! Yes, you will be a little anshus once you go in, but it'll be fine! I'm in 11th grade now, and yes I did get into 1-2 fights a year (and won ), but after that, you'll be fine. Just stay in shape and stay focused on school work!
