Recently I upgraded to MediaWiki 1.15 from 1.12 and now I see a new Special Page called Special:Tags. I am not sure what is this page for? The description "This page lists the tags that the software may mark an edit with, and their meaning." is not very self explanatory.
Do I know have the ability to tag my wiki pages which will appear on that special page? Searching online did not show any meaningful results.
Thanks!
