Ning-ing

I've tried it a bit

Ning's Infinite Ambition -- Viral Networks -- Viral Expansion Loop -- Social Networking Start-Ups | Fast Company

Just got it as for the name - n... an unspecified number.

So it's n-ing

But not necessarily a breakthrough, seem that it's similar to the old MCI "Friends and Family" promotion

Nevertheless - worth a try.
