If you really want to help OpenBazaar, help us make the tools to implement the OpenBazaar Market Protocol apart from the p2p network. This would allow users to create, sign, and verify the Ricardian contracts that OpenBazaar uses regardless of the network they are distributed on, as well as manage the multisig accounts. It's making online trade and multisig possible over any form of online communication. Read more about it here:

This will help the project far more than donations. Please reach out to me if you want to help make this. sam@openbazaar.org
