I am currently attempting to cobble together one of these of my deceased mother, whom I have years of text messages and all her journals (thousands of pages) plus audiotapes, which she left all to me.
Whether my brothers choose to participate, I do not care; it is not their decision, I am doing this locally on my own hardware (so the world doesn't learn her sufferings) and am really just curious. We'll see if she can continue giving great advice, years beyond her grave =D
