Widgetbox has launched what we are billing as our Partner Networks platform. The Networks enable publishers of all sizes to rapidly create custom, branded widgets that merge content across multiple sources, authors and feeds. The widget is completely customizable and based on your author feed(s). Partners format the widget (size, layout, content, etc) and then manage the content via our 'membership console' (a tool to add, invite and organize the feeds displayed in the widget).
Partners also get branded hubs on Widgetbox.com. Those pages are also customizable and dynamically feature the network's widgets, members and headlines.
