One line. It shows up to five of today's real listings and posts (volunteer openings, free events, lost animals, asks for help), refreshed every three hours, each linked to its source. No tracking of your visitors: the engine counts loads, nothing else. Free, and it stays free.
Community boards, libraries, block associations, church sites, school pages, a personal blog: anywhere New Yorkers already look. If your site needs a different size or a different set of kinds, say so at Support.
