This is the perfect application for you, if you want to create a sort of index or catalog.
Let's say that you have a board with users posting reviews of their favourite movies, music albums they like, tv serials that appasionate them or just a board used as 'market' where users post stuff that they want to sell in private.

NOTE: 1.6 is for invision power board 3.2 only AND it is only a minor update, few things have changed, this is NOT a major release. Do NOT install this version if your version of IPB is 3.1.4 or older, install the 1.5.1 instead. IF YOU DOWNLOADED THIS FILE ON Aug 12 2011, please donwnload this file again, since a bug was fixed.
Price tag is now 19 dollars.

=This plugin enhances IP.Board's built-in tag and prefix system,
providing custom styling and fine-grained control over prefixes, as
well as some helpful moderation tools. Prefixes are explicitly
created through the Admin CP, and can be chosen when creating a topic.
