A vocabulary (set of categories) can be supplied for users to tag their posts with (see Kairosnews posts for an example).

You can

• Try a sample vocabulary which has already been created.
  • Go to the taxonomy module in administer >> content management >> categories.
  • Select edit vocabulary to the right of "Image Galleries" in the the list of categories.
  • If you don't like "Image Galleries," you can give the vocabulary a new name (e.g., "Pictures")
  • Check the boxes beside the Types of content you want the vocabulary to be available for.
  • Note that the Required checkbox controls whether or not users have to pick a category term when posting.
  • Submit your changes.

  Now whenever a site user creates a post of one of the selected types, this set of terms (category items) will be available for them to tag their posts.

You can also

• Add terms (category items) to an existing vocabularly or edit existing terms at adminster >> content management >> categories.
• Create a new vocabulary via adminster >> content management >> categories.

By default, category tags are indexed on the Category Tags page. This page provides a live update of tags used on the site and the number of entries associated with each tag.
