Tagged offers a standard registration process. You need a couple of minutes to accomplish the registration task entirely. You can sign in via social media networks or fulfill an old-school registration form: name, birth, location, age, and gender. Also, the developer wants you to share an email and compose a unique password. If you use the application, there are different ways to join the community: email, nickname/password combination, iPhone ID, etc., to access the Tagged site or app.
