DESY workshop on Monte Carlo Generators for HERA physics Working Group 10: QCD Cascades Bulletin 4 We have now decided to hold the next group meeting on the date originally suggested by the organizers: Thursday the 3rd of September, 9:30 - 13:00. Since there are not many talks scheduled, we will most likely not need an afternoon session. In fact there is only one talk planned so far: "Comparing DIS and e+e- at moderate Q2" by Patrik Edén Please let us know if you have anything you wish to present at the meeting. Leif & Nick
