MEMBER ACTIVITY: At the moment the members are limited to just creating their profile and that's literately it, unless we have missed something? Members cannot create their spaces or posts which means there is virtually zero engagement which in my opinion defeats the purpose of a 'community'. Happy to see everyone suggestions on how to have an engaged community.
As an admin you can create a space, and users can join those spaces and create posts (if you allow). If you enable global posts from general settings then users can post globally.
Dan regular users in fCommunity cannot create their Spaces but they can submit any posts/comments in Public Spaces and/or in the Feed (if Admin allow posts in the Activity Feed by regular users).
If you give the fCommunity Manager role to any user the user can also create Spaces etc. If all regular users could create Spaces it would be a bit crazy to control and in that case you would need to have a single Space Managers not the whole Community Manager role (more granular access permission to manage - I think we dont have Space Manager role but Community Manager role).
If a regular user is being added to a Private or Hidden Space than the user can also submit posts/comments there.
ps. when I referr to a user or regular user I am talking about the Community User (not the WP-Admin user - since in WP-Admin the user should have a Subscriber role or the WP-Admin user should not have the Edit post role).
