From the help center:

 From dictionary.com because I didn't know what a flyleaf was either.

flyleaf: n. A blank or specially printed leaf at the beginning or end of a book.

Still don't get it. :)

Flyleaves are those blank pages before the title page.  It's certainly OK to post a book with initials or even other things written on the flyleaf or inside front cover. 

The only possible exception (I had a grumpy customer once) is those small "coffee table" books of collected quotes like "The Wit and Wisdom of Women" or "God's Little Instruction Book for Mom", which are usually given as gifts.  Even then, if someone orders the book and there's writing inside, just go ahead and send a message to the person regarding the book.  Remember the mantra that some people post to these forums - "It's a USED book site".

Thanks so much for the help. A girl at work gave me a book to post but it has her name in it.

I feel weird about posting it not so much for the writing but the fact that it is HER name that could now circulate around. Should I cross it off?

If she gave it to you and knows you'll be posting it, I wouldn't worry about that.  If it is just her name, and not any address, telephone, etc., I wouldn't worry about that, either.  And further, unless it's an unusual name, I wouldn't worry about that, either.  No one is going to know who "Kathy Smith" is. 

On the other hand, depending on how it's written, "crossing it out" might cause more harm than goodl.
