WikiAnswers was not specifically designed for kids, but it is intended for use by people of all ages, kids and adults alike. Kids are indeed allowed on WikiAnswers, and are allowed to have an account. Joining certain programs requires certain age minimums, though (for example, the supervisor program requires a person to be 15 years or older). Just keep in mind that there are certain categories on WikiAnswers that may not be suitable for children under 11-years-old.
