How this site works
You’re reading the book one page at a time, exactly as it will be printed. Notice anything — a typo, a doubtful fact, a confusing sentence, a bit you loved — and leave a note right on the page.
The screen
Chapters on the left, the page in the middle, comments on the right.
Page numbers are the same as in the printed book. Use the arrows, type a page number, or press ← →. The site remembers where you were.
You enter the PIN once per device. Click your name at the top right to change it.

- 5Private note to Jason, and this Help page.

On a phone: press and hold a word, then drag the handles.

It stays on the page
Your words stay highlighted with a numbered marker, and your comment appears on the right. Click any marker to see its comment.
Comments you wrote have Edit and Delete underneath. My comments at the top lists everything you’ve written.
Everyone with the PIN sees all comments — if someone already flagged it, you can skip it or add “me too.”
12- 1Your note stays on the page with a number.

Pictures and diagrams
Press Mark a figure above the comment list, then drag a box around the part you mean. The same form opens.

Whole page, or a private message
+ Comment on this page is for a note about the page in general.
Contact the author at the top sends Jason a private note that isn’t tied to any page — a question, an overall impression, or anything you’d rather other reviewers didn’t see.
12- 1A note about the page as a whole.
- 2Draw a box around a picture or diagram.
1- 1Only Jason sees these.
On a phone
Same thing, smaller. Press and hold a word, drag the handles, tap Comment. The comment panel slides up from the bottom; the bar at the bottom shows how many comments the page has.
The ☰ button opens the chapter list, My comments, Contact and Help.
A laptop or tablet is easier for selecting words, but a phone works fine.
Kinds of notes
Don’t overthink the label — the comment itself is what matters.
Jason reads every one and marks it Fixed or Read, leaving as is, sometimes with a short reply under your comment.
