I have just started using EN and was exploring how to create a hierarchy of stacks. To my disappointment it cannot be done. What I find more distressing about this product is that EN has apparently opted to not address the issue other than to say that it might, maybe, could be, possibly, something to consider in the future...or not. Then there are the EN evangelists on the different threads who subtly, and not so subtly, berate the rest of us for not adopting the organizational structure that is given to us from above. One poster even said that she learned by experimenting on the program daily and keeps learning something new and hinted the rest of us just need to buckle down and study more. I'm sorry, but I don't have all that time to invest. The cross platform access is great. But it doesn't override my organizational wants/needs. I need to be up and running quickly. If I had nested stacks available, I would have been on the road to purchasing, and implementing, a business or premium account. As it stands now, I am moving on to a different solution or going to keep doing what I am doing. I wonder how much business has been lost by people who just gave up and went on to other solutions and didn't spend the time to express their displeasure. Go ahead, keep preaching that we need to change our ways of thinking about organizational structure. I am moving on. Change your tune and offer nested stacks and maybe I'll be back.
