Hi James,
Thanks for the good wishes. In answer to your question. The site is very different from Thingiverse because in addition to being able share Cad files users can also collaborate on files, sell files and keep 100% of the profit, participate in contests and ongoing design league, easily find the software, fillament, printer or scanner that is right for them, offer/ provide a printing or scanning service, participate in our 3d printing course management system.... And many more great functions. I encourage you to explore the site and let us know how we can improve it.
Thanks and enjoy,
-Danny-
