// @description Searches forum posts for HIT links, follows them,
//              determines if the HIT is still available, and 
//              strikes the post if the HIT is ghost or changes 
//              the link text to show the automatic approval time 
//              if the HIT is available. Using this script will 
//              increase the number of page requests you make to 
//              mturk and may cause Page Monitor to give false alarms.
