At Brooklyn Brainery, they "host classes about all sorts of things: from physics to Australian desserts, from HTML to shorthand and just about every nook and cranny in between.
All of their course topics are dreamed up and suggested by you, and the teachers are a group of awesome people from around Brooklyn and the whole city.
Anyone can teach -- you just need a passion for the topic and a desire to share it with others. They do all the planning, taking care of sign ups, marketing, and materials, so you can focus on the important stuff (teaching, duh).
Classes are generally one or two weeks long, and they keep them as inexpensive as possible (something like $30 for a couple class sessions), because you shouldn't have to spend a paycheck to learn something new."
