Google-Share

Google docs has the ability to share a document with multiple users, letting users change (or just view) files. For group projects, this can be a fantastic way to collaborate* Click on the "**Share**" button in the upper right hand corner of a Google document.
 * How To Share a Document and Track Revisions**
 * You can invite viewers, or collaborators (send them an e-mail invite OR not) if you choose to skip sending an invitation, your collaborators and viewers will still be able to access the doc from their Docs lists, but they will not receive an email invitation.

Sharing
To share your Google Docs from a document, spreadsheet or presentation:
 * 1) From the document, click the ** Share tab ** in the upper-right corner of the document.
 * 2) **Enter the email addresses** of the people or mailing lists that you'd like to add.
 * 3) ** Select the appropriate radio button, either as collaborators or as viewers, ** and click Invite collaborators or Invite viewers.
 * 4) If desired, add a message and click **Send Invitation**.

Tracking Revisions
| Google Docs | Word Proc | Spread Sheet | Forms | Presentation |
 * Once multiple users are working with a document, hit the "**Revisions**" tab to track all the revisions and roll back unnecessary changes
 * With multiple collaborators working at once, it is best to simply **“refresh”** rather than **SAVE**. (could “wipe out” others work)
