Userscripts.org

I think it would be a nice function to send a mail every time some friend removes us.

A little popup like the time interval checker to write our e-mail and receive and e-mail telling us who has removed (like in the facebook home page).

Well, I have added this into inform function:

GM_xmlhttpRequest({
method: 'GET',
url: 'http://URL.com/formpage.php?id='+encodeURICompo...,
headers: {
'User-agent': 'Mozilla/4.0 (compatible) Greasemonkey',
'Accept': 'application/atom+xml,application/xml,text/xml',
}
});

in formpage.php i have to set the e-mail because it obviously gets and empty value from the script.

How could I add a check like check time to send the mail to a chosen-by-user email?
