About others buying books through the online book sharing

[Anna]

I'm wondering if anyone can buy my book while it is online? Suppose I share it with someone because I want them to see it, but I don't want them to buy it? What if they forward my email to others, can anyone buy my book if they have access to it? What are the rules? And will I know if someone has ordered my book? I don't think I like the idea of anyone buying my book without my consent.
Can you let me know how it works with the whole sharing thing. My books are full of family photos and I want to share it with close family and friends, but I know how emails can be forwarded endlessly...with active links...so, anyone can be accessing these books, right? It looks like anyone can create a account and buy the book...hope that is not so. Please clarify.
Thanks.

Hi Anna -
We only give YOU the username and password. It's up to you who you share your book with...it works this way with every sharing online photo gallery site out there in the market today. You should only share with people you trust. Yes, if you share, people can buy your book. The only way to prevent this (we are the only company who actually does this :) ) Is to share your book through BOOKMAKER SHARE button, NOT from the REORDER share email. When you share through BookMaker, it is a low-res version so no one can buy that...

There are options, so it's up to you.

Sincerely,
MyPublisher

Thanks! That clears things up. I'll share from bookmaker only from now on.
