i've just stumbled across a great way to proof read english text. i convert my text to pdf and use the acrobat reader's text to speech thing (view menu, read out loud). i otten make simple mistakes that MS word spell and grammar checker doesn't pick up, like a missing "I" or swaping "of" for "or". when acrobat reads it back it's much easier to spot mistakes like that than reading it yourself, well it is for me anyhow.
