Becomes a moderation issue quickly as a forum grows and can lead to a lot of drama (which increases moderation time) even in professional spaces. In the current state, everyone can see everything and make up their own mind.
I think an official discord/slack would be easiest. That way your contact isn't on a public forum. Just jump in a room you can link here and talk or chat and share info there if you want to.
