Well u wanna track ur victim or want to get his ip, location, browser settings, language or timings.... all u have to do is get his e-mail id...

Once u have it.

Go to www.readnotify.com

register there...

Once registered . . . send a mail to ur victim by the email id u registered at readnotify.com

But before sending the mail just add ".readnotify.com" with the victims id.. for example

xxxxx@yahoo.com.readnotify.com

and then send it...

when ever victim opens it his all the info will be mailed to u.

which can b very useful for the hackers.

Note = U can also change the settings in www.readnotify.com
