It usually means editing an answer. This is a feature given to anyone who signs in to WikiAnswers.
Technically, it is called recategorizing, and does not count as editing. Although you are 'editing' categories, it doesn't count as editing.
Editing is important on WikiAnswers for many reasons. The main reason is that without editing, it wouldn't be a wiki. Without editing, WikiAnswers would be like any other question and answer site - multiple, grammatically incorrect, jumbled, horribly spelled answers that have bits of information here and there and never gets straight to the point. Without editing, WikiAnswers wouldn't be a Wiki at all.
It might not be wiki. Other people can change them.
