To work on a document you want to share, just open the document on your computer. For the Word doc, you must save it in Word on your actual computer first, THEN add the NEW document to this wiki page. Click on the file button above to add a doc from YOUR computer.
If you want to make comments to each other, click on the edit tab (top right) and start typing IN THIS BOX to make notes to each other.

I'm only checking messages for me in edmodo...not here.
