Some brokerages elect to withhold their listings from various websites.
you may want to check to see if your listing can be found on other websites as well.
For instance the KC Star website http://(www.kcstar.com) has classifieds and there is a "homes for sale" section - you could check to see if your home shows up there as well.
You will have to ask your listing agent if their brokerage publishes their listings to all the available websites.
Good luck selling your home!
