Hi all! I have this idea for ecommerce platform where people sell their stuff to others. Sort of like ebay. It's supposed to be free for anyone, but if they want to, they could buy privileged status for their postings – that will be the monetizing model. How do you achueve this from a programming standpoint? I am working with mongodb and was thinking of having a separate collection of "featured" products that will be sprinkled in with the newest ones and thus be shown more often. If you know anything else or more about this, would you please share? Thank you in advance!
