Custom Keyword Stacking

Q: Can someone be so kind as to explain how the "Custom Keywords Stack" works in BLF. I think Brian mentioned it in one of the "Group" webinars but not in his one hour one? 

I really think some documentation which explains the functionality of all the factory products would really help? Thanks!

A: If you tick the "custom keywords stack" box then whatever keywords you put in the box under *for customer keywords stack will become the child folders. 

When you use the "primary keywords stack" box, then whatever you put in the first box under "keywords anchor text" will become the child folders.

I actually only ever use custom keyword stacks as they give me more flexibility with creating the child folders.
