Create a non admin area form to update user form I'm trying to see if there's an example of a form that isn’t in the admin area and is used to update user details. 

Is it possible to create this type of form? Where can I find such an example?
Look at the Drupal core user module, is generates the forms for account editing. Specifically, user_profile_form(), user_account_form(), &amp; user_profile_form_submit() will give you an example of an user-accessible form that updates a user account.
