hardcorehosting,
I've been actively promoting Oliver for 2 months.
So far 1 out of 3 has stayed to the second month. Which gave me $6 for the rebill.
I sold 5 the first month. One still hasnt got to the rebill time. and one was a year long sale that got me $50
He told me that his average is 4 months.
I'll have to wait a while before I can personally confirm that. But I think his sites content is good enough to retain members.
Plus there is no trial, so on a sale you make %50 of the $20 sign up fee.
