I actually bought and read the 2021 version of this, but it's not available to review, so here goes. There are so many good tips and reminders -- I used more bookmarks on this than most. I almost bought the paper book version of it, but there are also so many typos and other mistakes I didn't want to reward the authors/publishers/editors with my money. I mean, mixing up your and you're and not filling in a blank where a link was obviously meant to be placed. Totally annoying things that really took away from the helpfulness and enjoyment of the book. I'll be glad to edit the book for free if you need me to -- just let me know. ( )
