We need to build a website so that once registered users can fill out surveys that admin users creates to rate companies. The main goals are: - Admin users, being able to create/destroy surveys. - Users can register by email or facebook. - Registered users can cancel their account whenever they want. - Registered users can fill out surveys. In the absence of any data provided by user in the database (i.e. country, region, company name, etc), administrator users can approve or not this new registry to be displayed along with rest of options in future surveys. - Any user visiting the page (registered or not) can consult best or worst companies chart, being able to apply several sorts and filters we will describe in detail.
