This runs from 23 to 28 May. I have also decided to allow for people to decide which day we should attend. For this I've created a doodle poll to help select the day. If you haven't used this before you don't need to create an account to use it, you just need to supply a name & select which days you can attend. The poll is available at http://doodle.com/poll/bwnd3iewgrr853kk. I expect to decide in a few weeks which evening to run it to allow time for an announcement.
