Since Rupes was recently added to the list of sponsored forums, I was wondering what the difference was in vendor participation etc. between the "Sponsored Forums" section, which includes 3D/High Definition Car Care, Autopia-carcare.com, BlackFireWax.com, Griot`s Garage, and Rupes Polishers, versus the "Machine Polishing & Sanding" forum which is sponsored by Flex Power Tools, and the Optimum Polymer Technologies and Poorboy`s World sub-forums which are in a different section.
