What's your role? Network Creator (NC) or Admin?
I used to manage "The Sanctuary" with my team of volunteers. It was a private social site offered to folks exploring "dark culture" (goth/emo/vampire/etc), but the Ning price increases killed us. I was trying to keep it free and free of advertising, but the Out-of-Pocket became too much. My entire group moved to Facebook for now, though. I also Admin on a few other Ning sites.
