You can edit existing knowledge bases, e.g: add and remove categories, edit and remove posted records, move records between categories. To edit a knowledge base, do the following:
Note: think twice before removing categories and records, they won't be restored.
Important: after you made significant changes in your knowledge base, like removing a number of records or adding a lot of new entries, the search system needs to be re-indexed and updated to a number of new keywords. To do it, click Fix against the modified knowledge base.
To remove an existing KnowledgeBase, simply click the Delete link next to it.
