It's been years since we are dreaming of getting CCK into core. Dries has announced a code sprint, where six people are going to work on this for an entire week. That's 240 (wo)manhours and all we ask is a $7000 donation. This is your only chance to hire the top Drupal coders for less than a $30 hourly fee. If you have ever used CCK please consider donating the equivalence of one hour payment of your time -- it surely saved that many but likely even more.
