I can only speak of the system that I know but an advantage to our setup is that all the listings belonging to our agents link back to that agent's personal website - not the company's site. This ensures that are able to capture more leads yourself and it also helps with website search engine ranking.
Do you know if your office has an automatic feed? If not, you will have to enter manually. At the bottom of the page there is a link that to "submit your listings on Trulia". Click on that link and you will be able to enter yourself.
