 * This is a sample for userfunctions which can be used in PN. You allways have to return

 * it is recomended to use '@@searchstring'. 
 * It is checkt for each function seperately. So you may want to comment or delete an unused 
 * function.
 * To use this file you have to copy it to userfunctions.php
