Re: Zombie threads
Well, they're not deleted.
And besides, when a new poster jumps into a thread and attempts to engage either the OP or other contributing posters (none of which may be active here any longer), he or she isn't going to get much out of that. Better to lock the thread and suggest that he or she start his or her own thread in the appropriate forum in order to solicit feedback from active posters, IMO.
