There are three modules.
On the first module, the user logs in (via Twitter) and fills a brief signup questions, accepting terms of service and confirming its email address, as well as captchas. Once done, user has an option for submitting a quiz daily, to be sent by its twitter followers. Twitter followers may signup and answer questions, awarding credits to his friends.
On the second module, there is going to have a Swoopo/Telebid-like auction using those credits. There is a need to list prizes as well as participants notifications.
On the third module, there is a service desk where user may request for support.
