LiquidSnack, I totally agree with you on Thank you being nice. I'd rather have a poster come back, to post a short thank you if the solution has worked, than to see the thread is dead after I responded so I have no way of telling if my help was OK, or if the OP just lost his temper with my inability to help.
This is why I think a short "Thank you, I got it working" is far more important than rep from other geeks reading that thread. So please, dear fellow geeks, you don't have to rep if you don't want to. But take the time it needs, a minute or so, to post feedback. In my opinion, a good, solved issue thread (not talking about those forever living threads like Jokes or Post your desktops) is a thread started and ended by the same member; first post to describe the issue, last post to thank participating members for their input.
