Adopt a stencil:

Although millions of people have seen the stencils, they don't last forever.If you live near the site of a stencil and want to be involved, we're looking for people who are willing to adopt stencil sites and take over the responsibility of maintaining that stencil at the site. If you're interested in getting your hands dirty this way contact us and we'll show you how it's done and supply you with everything you need.
