LBRDRAGON  I have been using PlanBook for a year now and I am constantly impressed with it's abilities. The program is very user friendly and accepts a wide variety of schedule types; standard, rotating, etc. Jeff is always responsive to any glitches or problems with the program. He is quick to patch any problems that are found. Jeff is also constantly adding new features, such as syncing to iCal. As a teacher himself, he is aware of the flexibility teachers need in a planbook and comes through for us!
