WikiAnswers ranks your contributions by how many questions, answers, edits and community work you contribute to the WikiAnswers community.
Yes, WikiAnswers does have ranks. The 'ranks' are contributor levels, and if you make a certain amount of contributions, you are upgraded to the next 'rank' or contributor status level.
To get a new contributor rank, you must contribute more to the WikiAnswers community. For example, to get the Bronze contributor rank you must make at least 500 contributions.
The highest contributor level on WikiAnswers is Ruby Contributor (500,000 contributions or more). Community Assistants (Answers.com employees) could be considered the highest "ranked" on WikiAnswers. Scott Moore (username Struwwelpeter) is the head of the Community Assistants.
WikiAnswers does not pay for contributions. All contributors and supervisors are volunteers who love the site concept.
