Re: I would like to know, why replying to old threads is such a bad thing.
the original poster may have hung up, but often, the 15 other guys that posted to it many moons ago are still around. And there may be 10 new guys that haven't seen the info. I often find good useful info in resurrected threads.
A thread with good useful info has the best chance of being resurrected exactly because it has good info in it.
Or on the other hand, it may be an unanswered thread from long ago that is just now being answered, and OP is gone, but next guy asking similar question will get his answer.
