I'm configuring Business Portfolio theme as a front-end for a MU blog network. For my application, a social networking platform like BuddyPress seems too much because it's not geared toward a social network: http://eflyer.cc is the front end - so far. My goal is a network limited use sites that act a lot like RSS readers.
I observe the theme source code has modules to register and list blogs in a network and support for MU facility.
I'd sure like to access this functionality. Would you please guide me to docs that show:
1) How can I call the register utilities to create new users?
2) Similarly to browse and search MU blogs?
3) Is there an example/docs showing how to use a child theme to replace the "front page image" with a video?
