Look for the email button on top-right side of the toolbar. You can enable or disable this feature by clicking on this button. Your preference will be remembered when you re-visit the page. You can adjust the feel of the editor as per your requirement, whether you feel like sending an email or writing a document.
Trouble with email?
I reloaded the editor page after i deleted the temp internet files and all issues got resolved.
Email is a great feature BTW.
Please put the reference letter pad back next to the editor window for writing convenience.
Also please enable the option to post a comment without previewing it. I don't need to preview my comments all the time.
