How can I have spelling and grammar check function in my email compose?
For spelling issues, I recommend using Firefox. Firefox has a built-in spell check feature.





For grammar issues, you will need to compose messages in Microsoft Word or a similar application. However, grammar check features are notoriously unreliable, and you should borrow a book on English grammar from your local library. I am not being facetious!
