Create and share online documents, spreadsheets and presentations. It’s free. You can:
1) Access your documents online from any computer with an internet connection.
2) Add collaborators to your document and Docs will send them a link to access the doc online (no need to send email attachments back and forth)
3) Decide who can view and edit each document (only you, some people, or everyone)
