When you log in, go to the Social menu -> Party Members, right-click yourself (or subcommands on ps3) and edit your search info. Change your online status to "New Adventurer" - it's the last option that looks like a tiny plant. This is only available if you have less than 20 hours total of game time.

It's a brand new option with patch 2.16 and is a great way for more experienced players looking to help out others to find you. However, there isn't anything (yet) in game to help you find this option!
