For prospective joiners, Occupy D.C.’s Web site has a complete protest preparation guide, which includes medical — “Avoid Risk of Tear Gas and Pepper Spray” — and legal do’s and don’ts. (For instance, books, board games and digital cameras are among the encouraged items to bring; laser pointers and knives are not.)

For people with even more questions about protest survival secrets, Wired created this protest how-to wiki, which includes, among other tips, a step-by-step guide to digitally recording a protest. For more basic needs, Occupy D.C. supporters curate this digital map of bathrooms, eateries and other demonstration sites with an increasing number of bright red markers.
