I am learning how to promote http://codingforafrica.at/ in particular http://codingforafrica.at/help/
There is a lot of potential here to help, and I don't have big ambitions to scale this to a lot of children. There are also schools that need help. Other people that volunteer their time to run a daycare center for those that can't afford a regular one. One school is looking for someone to teach programming, but doesn't have the budget to hire a professional. I could volunteer to do it, if I could find a sponsor. It doesn't even require a full-time salary.
