That's an awesome point Jeffrey! Thanks for posting that ... if anybody has any questions about that and how to do it effectively please post because that is a great way to build a list without a product or any JV partners even...
The cool thing about this method is you create sub-lists ... I'm going to use IM as an example even though it's a tough market, but if you do this for copywriting, affiliate inferno, driving traffic, etc. those would all be seperate lists and you can then set up an autoresponder series targeted towards those lists where you give them quality info on copywriting and then suggest ANOTHER copywriting course because not everyone of them is going to buy the product you referred them to.
