Write the answer once, properly, somewhere findable.
WHERE
Internal documentation, or customer material.

Sending only a link reads as dismissal.

Documentation compensates for confusing design.

Whether writing it reduced the questions.
WHAT TO DO IF IT DID NOT
The material is not findable, or it does not answer the real question.

What words people actually use when asking.
WHY
They differ from yours, and search depends on matching them.

A collection answering the real questions.
WHAT MAKES IT USEFUL
