I would like to take this opportunity to thank all the speakers for delivering so well on the brief but also to all the people who helped make the day the success it was. I spent the whole conference videoing the talks and it is my next job to edit these and get them uploaded to the website. The first presentations from what has become referred to as the virtual part of the conference will be available in the coming weeks. There was an huge amount of information to take in on the day so these videos will certainly help me remember some of the finer points highlighted on the day. We were lucky enough to receive extensive press coverage courtesy of John Grant, of the East Anglian Daily Times, who featured a three part serialised report from the day. These can be read here: http://goo.gl/CBV5Yb http://goo.gl/WlUizW http://goo.gl/SwihQp One of the features of the conference was a preview of the soon to be published Suffolk Dragonflies atlas by Adrian Parr. This book, edited by Adrian Parr and Nicholas Mason, is now available to pre-order on the SNS website for £12 (inc. post & packaging).
