--Sell your stuff on craigslist without registration or logging in. Quick and painless. This is the first beta of CraigsPost. Please be patient and I will implement all the features you ask. Right now we support items for sale, personals, item wanted, community, event, gig offered, service offered, housing offered, housing wanted and resume/job wanted. We're investigating jobs and full housing.
