Click on People at the bottom of this page.
When the new page comes up, put Nazarene in the Denomination area. Then scroll down and click on Search.
That will bring up any people who had signed up as being of the Nazarene faith. You can look through their profiles and see if there are any teens or young adults you might enjoy talking to.
Just a note, sometimes really old people, like grandmothers, are fun to talk with also.
