When entering a new constituent, you have the option of doing a Full add, which allows you to enter data in all the profile page fields.

Or, you can do a Quick add, which is limited to name, email, address, and phone number fields. When you have finished adding the information, click on Save to create the new constituent record. If you have more records to add, you can click on Save and New to create another new constituent record that is the same type.
