If you are asking how to place your home on trulia as a "for-sale-by-owner"......quite simply - you can't.
If you list with a flat fee broker, they can also get your home listed here.
The only thing you can do to promote your home on trulia is to write a blog about it, and update it frequently or it will disappear from sight!
Craig's List is one site you can place your own home on.................there are others.
I am sure Trulia's "resident consumer helper" - Rockinblu - will come along and share his great link for marketing your home on your own...many find it quite useful!
Craigslist is best. http://honolulu.craigslist.org/rea/
I can send you some examples that do well for search engines, but you can see them yourself by going to the broker's area:
Midweek is also a good place to advertise.
