what happened to email link to a page in safari
are you asking about adding the Mail icon to the Safari toolbar?
While surfing the web and I found something I wanted to email I had a choice of sending the page or sending a link to the page. Now, after updating to Mountain Lion I don't have this option!
This is done using button number 3 on the toolbar (http://support.apple.com/kb/HT5364), if you don't have this icon, follow my instructions posted above.
