Your Realtor can enter it on Trulia if she has an account. When you do enter it, it says it may take up to 24 hours to be displayed, but usually it doesn't take that long. Sometimes if the Realtor is not the Broker, and the Broker claims the listing, then the Realtor has to check the box to get permission to also list the listings as their own. Then Trulia will send an email to the Broker asking for permission. That is what happens to me quite often.
