# Display UNIQUE Categories for Posts

 * I have 2 separate groups of Categories that a post can be classified in: Client&
   Medium.
 * I’m trying to display all the Clients (that have posts) and all the Mediums (
   that have posts), but not I’m actually displaying the posts.
 * The problem I’m running into that is that, if a Client has many Posts, I don’t
   want to display the Client more than once. The same applies for medium. If a 
   Client has more than one post in a certain medium, I don’t want to display that
   medium more than once.
 * Everything has to be unique.
 * What’s the best way of going about this? If I’m in the Loop, is there a way to
   only pull unique Categories? Or do I have to gradually put them all in an array,
   and check that they don’t exist before adding a new one?
