This forum has had a history with people bumping threads for really no good reason, which gets annoying after a while to have threads that are years old bumped for the sake of posting something like, "I agree," or, "Me too," contributing nothing to the discussion that was already dead to begin with. No, there's no rule against bumping old threads, but the concensus is that old threads should be left alone unless there's some kind of development that would prompt the discussion to start up again otherwise.
