For the discussion tonight it will be helpful if everybody could read
through the KDD data format; It's fairly technical and is not
trivial, so instead of spending time to re-hash it during the meeting
it would be great if we could all be on the same page.
Deadline for the challenge is June 8th, so we need to move fast if we
are to submit an entry.
Looking forward to tonight.
