When you write e mails on your hotmail account it is very important to keep in mind spelling so you won´t have comprehension troubles.
Although if you have a writing mistake at sending a mail to your friends or relatives won´t be important, it might if the receiver is a boss or clients.
For that reason, Hotmail has a dictionary and a Spelling Checker that allows you to know anytime if you had made a writing mistake.
If you have installed a Spelling Checker on your browser, just click on ¨Spelling Checker¨ on the upper side of the screen. You can also enter to this option by clicking F7
Now you can watch every word that is not registered or logged in the dictionary and click over them to see the different options of a good spell.
