+++ Tagging
Tagging is the labelling of items by people. Anyone can label and item and from that people can see and filter items based upon the tags that other people have given them.

At the side of an item you will see a field from which you can add a tag to an item. Say you had a set of wiki pages about sports. You can tag the swimming pages with "swimming" and the waterpolo pages with "waterpolo". You can now search for all items that are about swimming. You can also tag both sets of items with "water sports" or with the locations or anything you like that aids the categorisation of the items.
