Please tell me if this is possible...

You want to take your time and spell everything correctly and re-read it before you put it in the email venue so you write up that email using Word. You then delete several things you decide not to include and paste your final draft into your email program and send it on.

Here's my question: does the ghost of ANYTHING you've deleted stay behind? Can a savvy computer whiz look behind the document and dig up anything that was previously written and then deleted?

Thanks for your help guys
