I had qualms about their feedback system; My main concern was that since the market is only based on commissions , it could potentially lead to vendors padding feedback since they would not lose any coins as market fee. I have seen several vendors attempting this in the past, especially over at Nucleus and BB.
So Oasis have implemented a new feedback system with a vendor feedback page including the transaction value and total customer deals. IMO the more detailed feedback that is available to customers, the better choice we can make as customers.
And all of this has been implemented in just a few hours after I sent them a message with my concern - truly excellent stuff!
But I ask for a vacation mode setting a month ago and get nothing...
