1. i would like to know how to set up user registration and login for my site.
2. i would like to know how to go about setting up ONE MARKETPLACE in which the registered users can upload digital files for sale. let be be clear, i do not want the users to have multiple sites stemming from my marketpress site. i want them to register and then upload their products into ONE large marketplace from which i can take commission from the sale of the digital products they uploaded.
3. is paypal chained payments the only gateway that i can use to take commission, or is there another gateway to use? If so is it more user friendly?
