As a general reference, Trulia does not have a central platform to post/edit listings. Instead, listings are sent to us through a variety of feed sources such as partners, brokers, agents, third-party feed providers, or directly from an MLS.
Your listing, specifically, is being sent to us from Zillow, which is our partner site that sends us listings.
Any changes you are requesting to your listing on Trulia will need to be updated at the source, Zillow.
Thank you for using Trulia!
