I think it interesting - and somewhat disconcerting that you are planning on writing a survival related book, yet you are seeking material from internet forums.

What is going to differentiate your book from the hundreds (if not thousands) already published and not mention the tens of thousands of survival tips, training related websites, Youtube and others?

Do you have a background in bushcraft, survival training, SAR, or Military E&E training or experience?

Maybe give more of a backstory of what your book is about, then you may get some better input.

Same applies to your "Camping is love" post.
