RE: Editing in Gmail
Larry, it's easy.  After you hit Reply or Reply All you get a window that
not only allows you to compose your response but is fully editable.  To get
rid of all the previous post just hit Ctrl A (select all) and then the space
bar, you will then have a blank message to type into.  Or highlight the part
you want to get rid of and press the space bar and what you highlighted goes
away.
