Build a neighborhood marketplace named swapmeadow, for buying, selling and giving away things locally. - Sign up with a neighborhood. - Post a listing: title, price or free, category, condition, description, photos. - Browse listings in your neighborhood, filter by category and price, search. - Message a seller about a listing; each conversation is between one buyer and the seller. - Sellers mark a listing pending or sold. - Save listings, and get an email when a saved search has new matches. Seed eight neighbors, thirty listings with photos across categories, and a few conversations. Show the seeded logins on the sign-in page. Messages and listing status update in real time.
