System Builder lets you customize your website by adding a front-end menu for all your users, giving them a more flexible way to modify their user-information or to register new users. Also, grants users with administrator rights to customize basic fields or to add new ones.
To achieve this, just create a new page, and give it an intuitive name(e.g. Edit Profile). Now all you need to do is add the following shortcode(for the previous example): [wpsb-edit-profile].Publish your page and you are ready to go!
