Email This! Bookmarklet Extension

General Information
Email This! will send your recipient the link, title, & highlighted text of the page you are viewing using GMail, Google Apps GMail, Yahoo, and Stand-Alone Mail Clients like Outlook Express, Thunderbird, & More! If you hate toolbar buttons don’t fret. I’ve included a right-click pop-up menu and access keys!

Functionality
For Gmail
The Gmail Compose-Message page will open in a new tab.
The title of the article/webpage you are viewing will go in the subject line of your email.
The address/url will go in the body area of the email.
The highlighted-text will appear below the address/url

For Yahoo
1] Go To: Tools >> Add-Ons >> Email This! Preferences.
2] Login to Yahoo Mail Classic and look at the Url/Addres Bar
3] You should see something similar to: http://us.mc590.mail.yahoo.com/mc/ or http://us.mc590.mail.yahoo.com/ym/
4] Not everyone will have us.mc590 before mail.yahoo.com
5] Not everyone will have /mc/ or /ym/ after mail.yahoo.com
6] Write in everything you see in the address bar through the mc/ or ym/ (without http://)
7] For instance, I would write in us.mc590.mail.yahoo.com/mc/ (and nothing else following it)
8] Make sure there is an / at the end your input in the text box.
9] The extension will work the same as it does for Gmail and Google Apps Gmail after these configurations will be put in place.
