How do I use dictionary/spell check with email?

Depends on what email program you use. I use gmail and there is a button that says 'check spelling' under the subject line to the right. Also, I use firefox which automatically underlines misspelt words with a red squiggle (although it is telling me the words 'firefox' and 'gmail' are misspelt! so you have to use your common sense too).





Or, you could keep a site like dictionary.com open on a separate tab and check words as you go.
