decentralized anon market
you can put whatever you want to put on there.
Ya I just downloaded the wallet and it's syncing right now so I'm excited to check out this marketplace

Do people use PGP keys to give addresses and such out for when ordering something off someone? I hope so because that would be the way to make sure that people listing "Not so Legal" products the security that they would like when dealing with people on there

There is an encrypted messaging system, so you can communicate between buyer & seller.
And for transactions there is an escrow locking system -

I have provided brief overview / summary on how to use SlingRoad:
Right now the market is empty, but categories will dynamically appear based on the listings. When a seller accepts a buy request, they create a multisig address and fund it with a security deposit equal to the item price. The buyer escrow locks and also funds it with the item price, then the seller can request payment and the buyer can pay, which creates a transaction that spends the multisig funds to the seller.
