We are still accepting proposals for Lightning Talks and will continue to do so until a week before the conference. We will be having a Lightning Talk session, which will have about 10 Lightning Talks of 5 minutes, towards the end of each conference day.
It will be possible to submit a Lightning Talk proposal during the conference as at least two speaking spots on days 2 and 3 will be held open until the day before the talks to give you a chance to see something at the conference and put together a Lightning Talk response. As there will be fewer spots available during the conference we recommend that you submit your proposal as soon as you can.
If you would like more information about Lightning Talks please read R Geoffrey Avery's detailed description on the conference website.
