This weekend (21st-22nd May) will be the Drupal7Camp 2011 in Leeds and I have organised myself tickets and hotel to attend. Drupal7Camp is a barcamp that is devoted Drupal 7, and so will consist of talks and sessions from the attendees. As a result the actual sessions list will not be decided until the day and will also consist of some informal discussions and workshops.
I will be representing #! code at the event (probably with my #! code t-shirt) and will be giving a session on the use of the new queues functionality in Drupal 7.
