How to ask moderator a question

Greetings – How do I go about asking the moderators a question in private? That is, not on a public page? Is there an email or contact form?

FYI: I asked about moderation in a public forum and part of the answer from a WP Moderator was this: ”?Asking about it in public is not helpful. “…but I don’t find how to contact moderators except in public. Hope that make sense.

Thank you,
Kim
