The development and deployment of this microsite is realised with the WebEngine CMS combined with Java/JSP and MS SQL. Also for the more complex user management of all the participants, the 'Visitors Module' of WebEngine proved to be a strong solution (keep count of the number of points, number of challenges and invitations, downloaded reduction vouchers, etc, ...).
Further on a lot of attention was given to the user-friendliness, clear and intuitive navigation and the design of this site. Especially the Gamma game 'Supershopper' is a masterly example of Flash and Action Script 3 development.
