I wished that I was on their lists when I first started out in the IM realm, these 2 studs are the real deal and their content are always top notch and they provide so much free yet GREAT/Top scale information that can benefit people on all levels.
If you are a newcomer, then make sure to get on their lists, if you are a person that does well in their business, still get on their list and learn.
