The first 200 open seats for the Essex Design Summit were registered in less than 9 days. This event, geared towards existing and prospective OpenStack developers, is separate from the OpenStack Conference and has a more limited capacity. For the last 50 seats, the Design Summit organization committee needs to give priority to OpenStack core developers and well-known contributors that missed the boat, so we set up a waiting list.
This list will be reviewed regularly, and people that are confirmed will receive an email. The last 50 seats will be gradually assigned over the next weeks. If you want to make sure to have a seat at the OpenStack Conference, you should probably register for that event separately, since there can be no guarantee you will get one of the last Essex Design Summit seats. Sign up early on the Summit waiting list to increase your chances !
