As teachers, we have many roles: instructors, counselors, air-traffic controllers, role-models, chief cooks, and bottle washers. . . . We shouldn't also have to be deep-pocket donors, buying all of our classroom supplies. That's why we love the word free, especially when it relates to writing resources. And free is best when it means not just "free of charge" but also "free to use, modify, and share." Really and truly free.
