In many situations
it really doesn't hurt
to ask the person we believe
is THE domain expert
Details
Domain experts are the people who know most about the subject matter.
If you don’t know who to ask directly then you can try using Stack Overflow, an official support channel or an unofficial channel like Slack.
Before doing so, make sure you provide enough context for the experts to get their teeth into.
Don’t forget: It’s possible that you could be the domain expert.
