WikiAnswers has no "Contributor of the day"
A person can become an Expert contributor in Wikianswers by asking and answering a lot of questions.
You just ask or answer a question, and you automatically become a contributor. If you mean how do you get the badge that says "contributor," you have to sign up for the site. Any registered user who hasn't moved on to a different badge will have the contributor badge.
The more you contribute (answer, recategorize, etc.) the higher ranked you become if you contribute enough you become contributor of the month. Remember you need to have a WikiAnswers Account for your contributions to be logged
200,000 contributions

There are badges on WikiAnswers because each badge symbolizes the work one particular contributor has put into WikiAnswers. The more badges, the more associated that particular contributor is with programs of and with WikiAnswers. For example, a Supervisor (category or floating) badge shows that a person is dedicated to patrolling WikiAnswers for vandals and what is out of place and what shouldn't be on WikiAnswers. Another example would be the SPA (Special Project Assistant) badge, which shows that this particular contributor helps with small projects around WikiAnswers to make it better that most contributors are to busy to take care of completely. Basically, the badges show the dedication and time a particular user has put into making WikiAnswers a better website. See the link below.
