Just remember if you want your website to be useful to new users they must be able to find your website. The main way people find new websites is by using Google. Google indexes content into its search engine and its spider mostly collects content. Although you have a Social Networking Script that operates just fine and could have a lot of unique content posted by its members, Google cannot see this since the Google spider doesn't have a login ID to your website. I suggest that you post your project on Scriptlance.com, multiple search engine marketers and SEO (Search Engine Optimization) pros will bid on your project and they will get your site a page rank which will lead to you being able to sign up for Google AdSense. Let me know if that answers your question. Thanks, Virgil
