Another thing Iasonas:
  Once you have an "open" item bank, is it useful to calibrate the items? the difficulty of the items will ve reduced, even most of them will be solved by mostly all people...so the initial calibration has nothing to do with the original calibration.
  This is another important topic to discuss.
