Beckie and I have been working on the data during the last few days, and we hope we can wrap this up soon.

Even so, we still do not have a schedule or date by when the results will be made available. Sarah (Slim) and I have asked him to provide one. I have also asked whether there are any plans for future editor surveys, and if not, why not.
Watch that space ...
