We encourage users to get contribution points by contributing to the site in a positive way that they enjoy - whether it is answering questions, asking questions, editing questions, editing answers, categorizing questions or anything else on site.
New users can't improve a question on WikiAnswers. After they have made 100 contributions, they can edit questions.
It is considered a fair amount. Many users contribute once or twice and then leave, so 100 contributions tell us that you are active on the site.
WikiAnswers ranks your contributions by how many questions, answers, edits and community work you contribute to the WikiAnswers community.
WikiAnswers does not pay for contributions. All contributors and supervisors are volunteers who love the site concept.
