If you wish to save something under another file name, then open a new file and copy the paper into it. This is how we will be using it. You can add further comments while you are reading. When the D button lights up, that means a new comment was just added. You should add thoughtful comments to several postings, perhaps beginning with those written by students whose names are closest to yours in the alphabet.
Messages are for private communications.
If your M button is lighted, that means that you have a message. I just might be from me, as this is a major way that I will communicate with you. To change assignments, click on the A button and choose the new assignment. We will be working in at least two groups for a while. That means you will see the postings and discussion only from your own group.
