Referral Membersip System with Replicated Marketing Pages See attached document for full description Hello, My name is Ken. I used a system like I am describing in the attached document for many years. What I liked most about the system was that I had an unlimited number of tags that could be customized by either me/Admin or by members via their Member Control Panel. I had full design control over the Member's Control Panel and the replicated marketing pages. I simply inserted the tags/codes in my web design to customize the content of the pages with the saved info from the members. I think I prefer the use of Perl and MySQL, if possible. It's what the old system was built with. Important: I want to use .html pages and NOT .php pages
