If you are planning to attend the conference as a standard delegate (i.e. not a presenter), there is no deadline for registration. As long as space is available at the conference, you can register right up until the conference itself. You can check the homepage of the conference website (which you can find here) for announcements about the conference being/becoming fully booked. If you know you are going to attend, we do recommend that you do it as early as possible. As well as ensuring your place, this will mean that the Conference Project Lead will be able to send all the relevant documentation to you in good time before the conference.
