I have created a wiki stub session for you and also added what we have so far - the summary will need to be changed, but you can expand there with all the details coming in.
Can you keep the points which you think the discussion should go into? Those not so important add them in the comments, or discard?
That will help us when we invite new people.
A good date for this event for me is the last week of May, how about for you?
