Hey jdownloads, I know you asked for five sites, but I have one I would like to submit that has nothing but great information and that's makepeacetotalpackage.com This site is one of my favorite places to visit to get free information from people that know what they're doing. This site covers everything from copywriting, offline and online marketing, affiliate marketing, list building, ppc marketing, web design and more. And it's all for free. It's ran by Clayton Makepeace, one of the worlds most well know copywriters. Plus they have tons of experts in all fields of marketing that do guest posts. I hope this might help a little. Brad
