I do like the flow. One thing though - your intro is defining how to *pivot* (how to turn 3 rows into columns), NOT how to un-pivot. A bit silly - but it can be a little confusing if you're not familiar with the concept since your technique section then describe turning the columns back into rows (which is the actual unpivot part).<b

Your lack of planning does not constitute an emergency on my part...unless you're my manager...or a director and above...or a really loud-spoken end-user..All right - what was my emergency again?
