In "Spelling and Grammar":
"At present, the book is in a raw and constantly in progress state."
Maybe this would sound better:
"At present, the book is in a raw state."
Or
"At present, the book is a work in progress and is still raw."
In "Chapter/Content Suggestions"
"If you had any ideas for subject content in the book, definitely let me know."
Should be:
"If you have any ideas for subject content in the book, definitely let me know."
