UPDATE -- 21,473 people have registered for the ETHB airdrop, which is scheduled to take place on 2/14 ... sooner if we get to 100,000 registered before then.
I've created a new EtherDelta guide which has been sent to everyone who has registered. This guide explains how to use EtherDelta, step-by-step, including how to create a MyEtherWallet and how to Buy and Sell ETHB. You can read it by clicking https://etherbtc.io/etherdelta_ethb_guide.pdf
After the airdrop, holding 100 ETHB in your registered wallet will allow you to participate in additional airdrops when other projects hire us to deliver their tokens. We don't know how many projects will hire us for this purpose but holding at least 100 ETHB will allow you to participate in future airdrops.
This will give ETHB the benefit of airdropping additional tokens similar to how holding bitcoin allows you to receive free hard forked coins. Pretty cool, right?
