Good question, Joel (Salesforce) - I should have been more detailed. Our current Community is in Salesforce and managed by another team. I have a private/unlisted, advocate group of members. My opportunities are limited in the way it's structured (replies are collapsed, there's no notification when there's a new post, etc.).
I'm looking for a way to build a private member community such that we can accomplish: Communication updates and advocacy participation opportunities (from my team to all advocate/members). Questions, advice, ideas from one advocate to the group (post), or 1:1 engagement for members to ask/respond outside the entire group ("I'm in healthcare cyber and you're in healthcare cyber, can we discuss how you approach xxxx with the platform?")
