Hi, I agree that it would be beneficial to digest the first challenge. I would for example like to have the time to read the papers that describe the various approaches. Also, with many proposal deadlines in the US in January and early February it would be very hard if not impossible to participate in this upcoming challenge.

So we are seriously considering withdrawing from the second challenge. Carole > Hi Simon and all: > > Re. the 2nd Prov.
