Stan,

Nice step-by-step article with some timely graphics to show how to do things. Although it wasn't specifically named as such, I believe that folks will come to realize that this is a very good "spackle" article that demonstrates the beginnings of a technique. Like any "spackle" article, it's not meant to be a complete solution but it'll sure get some thought juices going for people who have ever had to import "unknown number of columns" files like I've had to do in the past. You could have saved yourself a bit of commentary by identifying that the popups where there only for verification during development and, perhaps, more clearly identifying not only when this technique might be used along with suggested "next steps", but it's a good article. Thanks for taking the time to write it and share it.
