I'm willing to bet that Most marketers like you (and me) have more places to market our promotions than fingers and toes together. One I think you should put on the list, if you haven't already is 'Tested and Proven.com. Klaus Biesel and Penny Cannon have created an amazing site centered around fourteen excellent mailers including Leased Ad Space which you'll be surprised to know costs you zero dollars to join. Another strong feature is that there are no emails to read, just promote TAP which automatically promotes the 14 programs in the downline builder for you. 

Because Klaus and Penny see clearly the value of LAS, several of their splash pages target LAS with statistics they've compiled that show clearly how TAP pushes LeasedAdSpace for signups. It's a powerful tool to accelerate your LAS business and the entire downline builder. I often remark that joining a program "Free" is a very costly way to conduct your marketing business because you deny yourself all the marketing benefits of the program, but in the case of Tested and Proven, this is the exception to that rule.
