 * Hi all, what is the best version safe way of checking that a category exists 
   and then maybe inserting a new category from within a plugin?
 * I have read that using the API to do this is the best way, the function category_exists()–
   there is just one problem with this though.
 * This is in the admin functions, and so when the plugin is triggered by a ‘normal’
   surfer, the admin functions havent been called and relevant permissions arent
   set, so I get the error message Fatal error: Call to undefined function: category_exists()
 * So, do I need to write entirely new functions, one for version 2.3 and one for
   2.2 and lower, or is there another API function that I have overlooked?
 * Thanks…
