F. BuddyPress MultiSite

This extends BuddyPress network instance from one site or subsite to multiple BuddyPress instances in a WordPress Multisite installation. This setup is complicated and would require BuddyPress/WordPress expertise plus server administration skills. You would need to install plugins to be able to configure this set up such as:
– BP Multi Network (WordPress plugin repository) or
– BuddyPress Multi Network (BuddyDev.com)
Please post in the respective forums if you would need assistance with either.
