Maybe this is more a curiosity than anything, but I have been reading different posts and random questions pop into my mind. If you have time, would you mind answering them. I understand if you don't have time.
1) Will your oldest ds finish all the guides that you have planned? If not, does that make you feel sad? (I ask because I am not sure my ds will be able to do them all and it makes me a bit sad....

2)Was your original intent for HOD to be used as a combined curriculum for multiple ages or has it just morphed that way as you have decided to continue writing more guides?
Like I said, I know you are busy, but I have noticed that you are pretty busy on the board today so I understand if you don't have time to answer. Maybe Julie would have time if you don't.
I live overseas and one of my ministries is to help our co-workers if they have questions about homeschooling or different curriculum. If they are still in the searching stage or the Lord is calling them to use something new, I am encouraging them to look at HOD. We now have 7 families using HOD. With other ministries that we are involved in over here, we find the guides so easy to implement, just as you intended.
Thanks again,
Sherry
