It looks like Irina and I both posted our answers at the same time and I want to make a correction regarding her answer:
Listing management, which includes the ability to add, remove or update listing information and photos directly on Trulia, is completely free of charge to any professional who has claimed their listing on Trulia.
Please be sure to let us know if either of you have any other questions.
Several of your listings that are in a sold or expired status on Trulia can be updated manually within the My Listings section of your account located at http://www.trulia.com/account/listings. For those you should see a drop-down menu that will allow you to change the status to Active, or the option to resubmit the listing.
If those options aren't available for a listing that is still live, our Customer Service team should be able to reactivate that listing and give you more information regarding why it's status was changed. Please reach out to our Customer Service team either by phone at 888-466-3501 Monday - Friday 7am to 4pm PST, or by email via the link below.
Try to claim your listings through Trulia.
Once you claim them, you should be fine.
Also, if you have Trulia paid services, you have a control panel where you can change the status of a listing.
Sometimes, the "feeding" sites choose what they put out - and do some but not all listings...
Hope this helps!
