I'm somewhat new to this forum but have been Ubering for nearly 18 months. To date I have accumulated nearly 12,000 total "stars". I've scoured the interwebs and can't find this info anywhere so figured I'd ask here. My question is, uhm, does anyone here know how many STARS I must acquire in order to exchange them for something of actual value? Is there like a "Stubhub" or Craigslist for stars that I can trade them in for something more valuable, such as concert tickets to Styx or Cubs World Series Tickets or anything like that?
