Hi folks,

I have been wondering for a certain time what can be done concretely
with cross-site scripting. I mean, for example a Web
page on which I input an incorrect email address which results on a
page which says "your address [string entered] is invalid".

I can eventually generate a Javascript alert box containing my
own cookie, or things like that, but that does not have any
advantage for me.

I understand the interest to use XSS on message boards or others,
consultable by many people, but on simple pages like that, which I am
the only one to see? What can be done?

Thank you for your help ;)
