Re: Need for hierarchical groups
I know BuddyPress is designed to to extendable. So is WordPress. But this is core functionality. Just as WP has hierarchical pages in core, BP should have hierarchical groups in core.
I’ve created a ticket for core developers’ consideration: https://buddypress.trac.wordpress.org/ticket/3961
P.S. As for propagation, the plugin author says it’s a very popular request, but he won’t do it http://www.generalthreat.com/2011/12/extending-groups-hierarchy-join-upstream/
P.P.S. I don’t know how well this plugin is working. Has conflicts with Registration Groups, and potentially others
