I got asked this:
Going to organize a series of open, and free, events covering WebGL / Web API [...] We ended up opting for an educational workshop format. Knowing you have experience with WebGL, I'd like to ask you if you woudl support us in setting up the materials [...]
In the interest of helping more people that might be wanting to start a WebGL group in their town, I'm posting the answer I gave them:
Now you know how to do this. Go and organise events! EASY!
It's actually not easy.
