Prior to that group, they had an online community for teachers looking for lesson plans.

Sell photos. If you have a decent camera and a good sense of light, color, and composition, you can take and sell stock photos – i.e. nondescript images that lend themselves to many applications and are commonly used to illustrate online articles or products – with minimal effort. Stock photos of locations (a fire hydrant, a bare wall near an interesting tree, or anything you might find as a default background image on your computer) are easier to take, but stock photos of people (i.e. people arguing, people kissing, people laughing) usually sell for more, as they have more uses and require the written legal consent of your subjects. Hunt for a reputable stock photo dealer or database that will pay you fairly before signing on with anyone.
