Why can't we use a free word processor?
We can. Look up Open Office. It is a complete suite including
software for creating presentations, spreadsheets, and databases,
as well as a word processor. All of the formats are Microsoft
Office compatible, so anything created in Open Office can be opened
and manipulated in Microsoft Office and vice versa. And best of all
it's totally free! I believe the website is openoffice.org. Check
it out.
