Question 5:
"I entered my information, but I do not see my profile online at my city. Why is that?"

You probably only filled out the contact information for your profile. Once you have logged in, select "Edit Profile" from the menu. Then there are two other sections for you to fill out. One will ask you about your preferences, and another will ask questions particular to a roommate, a tenant, a landlord, a traveler, or a host. Once you have entered this information, search in your area to see your profile.
