You are still a Guest member. You need to finish your registration and be confirmed as a Family Member. In order to do this you need to create your Tags and Volunteer. On your Navigation Home Page you will find boxes labeled "Tag" and "Comment." In one or more of the boxes labeled Tag, enter one of the surnames in your family or locations that you are researching. Underneath that box enter in the Comment box how they are related to you. For example, you might say that a surname is in your maternal family line.
Scroll down until you see the bar that says "Add Tags and Volunteer." When you click that bar, that will tell the greeters that you want to become a member and one of them will come by and confirm you. For more information on volunteering you can check out this page on Volunteers.
