Sometimes at work I need to send a web page to a co-worker. What I want to do is make a script that is client side (preferably in java script) so I can put it on my bookmark's toolbar and when I click on it, it automatically puts the URL in the body of the message and sets up the subject for the e-mail.

My problem is, I cannot get the string of the previous URL and if I try to use the current url, it wants to use the URL of my script.

Is it possible to do what I want and if so, how?
