WHAT TO DO BEFORE ASKING

WHAT TO PROVIDE
The exact message, not a paraphrase What you were doing when it happened When it started What is and is not affected
WHY THAT MATTERS

WHAT NOT TO DO
Continue trying things that might make it worse Hide what you did before it broke
THAT SECOND POINT
What you did is the most useful information available.
