Using AJAX in Tabletop

Early in the design stage of Tabletop we decided that we wanted it to be fast to use, and that would mean using AJAX to perform functions without loading new pages. Over the last couple of days I have been learning how to use AJAX. The best tutorial I found was at w3schools. I have been working on the "Edit Profile" page. Data is collected on a form and sent to a PHP file, which validates the data before saving it to the database. An appropriate message is shown to the user on the original page.
