title: WordPress - Add New Option to Categories
body: <p>I have some experience making WordPress plugins, however I am now trying to make a plugin that adds a new field to an existing WordPress function.</p>
  
  <p>Basically, when creating categories, I want to add a field called "alias" where a user can specify an alternate title for a category - so one category might be called "Questions" AND "Q &amp; A".  This new field would have a supporting template tag, so it can be pulled into a template where needed.</p>
  
  <p>Whats the best way to add this functionality into a plugin, so it can be activated and deactivated as needed?</p>
  
  <p>Thanks
  Zach</p>
