help me pls...

ok, well basically credentials in cloudcrowd is just like a credentials on your school, you need to pass a series of test to get the next test, in cloudcrowd you just need pass an available task and be approved, there are different skill categories like a reviewer, editor, researcher and other, you need to pass one available task first for a certain category then you will be credible to take another task of the same category. for example, you had taken the Review Websites task, if your task be approved you will be eligible to take the Review the Reviewer's Review task, and other Review Websites task, if unfortunately your task will be disapproved you will get a negative score that will affect your credibility and would not be able to take any task in that category. Hope that helps.
