When a user views HUKD after some time there are obviously pages to sift through. The task of picking out what is helpful is made more difficult by the reams of EXPIRED deals. One easy way to deal with this is to delete these threads once a deal is expired but obviously there is much conversation on some of these deals even when they have expired so this probably would n't be acceptable. Maybe move them to a different area or perhaps most acceptable can they be changed to a different colour so these can just be then skimmed over by a viewer unles they are looking for a particular expired deal? Sometimes a page is made up of as many expired deals as current ones.
Just a thought.
