It would be helpful to have an edit feature in the 'my books' page to make price or quality changes easier

It would be cool if I could enter my email and the book I'm looking for and then get notified when someone offers to sell that book in my town.

add a section that allows us to write a description of the book.

Allow the seller to change or erase his/her profile. For example, update e-mail, password, phonenumber, spelling of the name and everything else on record.

When you enter the ISBN number of the book, it would be nice to get a suggestion as to how much other people are selling it to set an appropriate price.

after selecting a city, allow to select the whole country again.
Many cities tell "all books have been sold". Not a problem if the list would give a number of things behind the city. e..g Toronto (5) meaning 5 books.

this page is very long. can you make it small like yahoo.com or dmoz.com?

Thanks

Since the website is so usefull, come up with some idea to market it in each and every universities and colleges. I am ready to help.

It would be helpful and save time if a link to publisher's website was added when listing a book.
