Why are so many old posts being bumped up again?  They are jumping 2 or 3 years.  Surely the person who first posted the problem has solved it by now or has a different horse.

My observation has been that others are bumping up old threads to ask for help with the same problem as the original posters on the 'old thread'.

Hope this helps!

What Clay said ^^^^, or when someone is asking about something thats been discussed I will bump the old thread up to help them out with that question thats all ready been asked. Or an opinion is being asked on a subject thats been discussed will bump up a old thread. Or its Spam thats bumped up a thread.. And sometimes theres some really good threads that needs a bumping up for old times sake as a reminder of something good. 

I think it is Spam that I am seeing bumping up the old posts.
