Still curious about this books with different ISBNs thing. 

1. Posting on the "Different ISBNs" thread in the book bazaar seems like a pretty hit or miss way to get the attention of the people wishlisting the similar book.  Besides, those people already got a notification of the availability of your book, right?  How does posting there generally help?

2. Why do the posts on that thread include the ISBNs?  All the poster has to do is mention the title, and anyone interested can look on their bookshelf, yes?

Thanks.

People mention the ISBN so you can add it to your wishlist if you want.  And no, that notification email doesn't always work because sometimes the title isn't EXACTLY the same.

I think it's worth it to post in there.
