Dear fellow #IT people. I know we all hate it when users give us vague error reports like "it's not working!".
But how often do you go out of your way to thank them when they get it right and send you an error message with a screenshot and reproduction steps?
If you don't do this already, I highly recommend starting ASAP. Even for the most technical users, it's helpful to perform this simple action as *positive reinforcement* for doing things right. Training users to be better at their jobs makes all of *our* jobs easier as a result.
But, as an added bonus, people seem to like being thanked! So, it also makes them like you more as a side effect ("oh, (s)he's not one of those grouchy IT people!").
