We use both a Facebook Page (existing) and a Facebook Group (to be created/merged).

Possible names for the Group (if we can't merge and even if we can):

• ClassicPress Developers
• ClassicPress Community
• ClassicPress Group

I think the group should mainly (but of course not only) be an instrument for Developers to interact with other Developers, much like the existing Slack Channel programming.

A place where the more expert helps the less expert, and people can come to ask “pre-use” questions as well.

This gives an incentive as of why to join, and simultaneously promotes the brand awareness.
