OpenLedger is a company that has built on top of the bitshares platform, as have many others now, but it was the first gateway. I would suggest opening a new account on a bitshares wallet that has been specially created for this project. It simplifies the procedure (it is still a little complicated if you are not used to the bitshares ecosystem).
