Wikipedia and Wikia co-founder Jimmy Wales has just joined the advisory board of CK-12 Foundation - a nonprofit organization that provides standards-aligned online textbooks to kindergarten to grade 12 students. One key element of the organization includes offering "FlexBooks" - a product that allows educators and students to create and edit their own open-content teaching materials. Users can add chapters to existing texts or create completely new material using the Flexr tool.
