To edit, update, or remove your Community Board listings, you must first create an account (Find out more about Community Board Accounts). If you do no have an account, any listings you add cannot be changed or removed.
To remove a listing, login and click on My Listings. Click on the title of the listing you want to remove. If the listing is Pending, scroll to the bottom of the page and click Cancel Listing. If the listing is Active, click the Remove Listing button that appears to the right of the ad. The listing will be removed from the Community Board and will now appear under Past Listings.
