The BlockParty is on!

Hello. Thank you very much for signing up for CodeUp#21.

As the Ether price goes up, the interest to this group also surges and this is the second time in a row that we have people on the waiting list.

If you have registered but unfortunately cannot make it, please make sure to cancel your spot so that people in the waiting list can get your spot.

As some of you may know, I've been developing a Dapp called BlockParty to solve this kind of problem (If you aren't familiar with the dapp, please see the github repo and my talk at London Ethereum Meetup).
