No, you just have to be consistent. A little bit every day is the easiest way to get there.
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
