Much of the process that makes any Wiki into a really useful resource, is the degree of maintainance that it receives. Wikis benefit from constant intervention to correct, add, reorganize and generally edit the content.
Generally this is left up to the readers and regular contributors. However, we have made the distinction in these help pages between adding/changing the contnet of an article - and the organization, or re-aligning the pages and links. We should also consider the adding or cleaning up of Categories attached to an article.
