[NTG-context] ConTeXt meeting Lua tutorials

Hi all, Today I started preparations for my activities at the ConTeXt meeting. There are two small lua tutorials in the program, and I am looking for input on both. There is one that is supposed to be a general beginner's introduction, and one specifically about fonts. For both, I am looking for input on what subjects I should cover? Since both tutorials will end up as articles/wiki pages, it makes sense to ask everybody on the list for input (but requests by actual attendees will be scored considerably higher). Best wishes, Taco
