You can do this in two ways. The easiest way would be to use the Classlist link on the red toolbar in your course window. Login to your course and click on the Classlist. Scroll down the list and select your group members by clicking on the box next to their names. Then click on the letter icon button at the bottom or top of the list. This will add them to an e-mail address box in a new e-mail message window. This can take a moment or two. Once the window opens type your subject and message and hit the Send button in the bottom right corner of your window.
The other way is to use the Email you access at the top of the course window on the blue toolbar. Click on Email then click on Compose. This will open a new window that looks very much like other email services. To find your classmate's email addresses click on the Address icon at the top of the window. Click in the boxes next to the names of the people in your group. This adds a check mark to the boxes. Next, click on the To, Cc or Bcc at the top or bottom of the list. Selecting To is fine. Then click on the Add Recipients at the bottom, right of the window. This last step will bring you back to the email window where you can type in your message and or add an attachment. When you are done click on Send.
