Telling your friends about a great webpage you have found is easy. You can use Mozilla to send the page itself (as HTML) or just a link.
It could not be much simpler than this:
Open the page in Mozilla and select either "Send Page" or "Send Link" from the File Menu. Mozilla now opens a new Mail Compose window that is ready to be sent. All you have to do is type your friend's e-mail address, add your personal message into the body and press send.
