Hey, @whatsup. The scrip have unique codes on them that can be used to register a Steem account using our faucet at https://portal.agoric.co.
For this first round we are looking to raise funds to cover the costs of registering 3333 Steem accounts using our faucet (without delegation). In the future, we are considering turning this into a managed service that will allow anyone to fund their own scrips; we will handle the logistics of printing them and mailing them to individuals or groups that wish to utilize them in their own initiatives.
We will also likely utilize delegation in the future, however considering that these invite slips are going to be given to people physically in person, we also think it is a nice gesture to give them about $5 worth of STEEM when they create their account, as a method of further distributing STEEM stake.
