Ok this is a kind of weird idea too explain but basically you can edit or input information on the page with a simple click of the button so if you see something you would like to edit just click it.

I think its best if you read the quote below and then visit the site:

Edit in place (also called in-place editing) follows the axiom Alan Cooper calls “allow input wherever you have output”. The combobox a form element unfortunately absent from HTML demonstrates this. In the same place where the current selection is displayed, the user can enter a value directly.
