Just about wherever you live, you can find a local or nearby version of the Craigslist online classified ad service. Whether you’re looking for a job, trying to buy used furniture or searching for human companionship, Craigslist provides community-specific sites for more than 700 cities in 70 countries. If you can’t get your emailed response to one of these postings to go through to the person who originated the ad, you can trace your communications malfunction to your computer setup, the status of the ad or how you craft your reply.
