JV sites are amazing creations for promoters like us.

You will certainly want to join Kenny Lessing at his many sites for he cranks them up like nothing. 

Most of the sites you're seeing here on Band of Banners are creations of his -- either sold or rented out to happy Owners and Admins. 

Here's but a few of his own "Real Time" sites which boast of a HUGE membership base:

Real Time Mega Traffic
Real Time Surf Ads
Real Time Auto Surf 
Real Time Ad Blast
