On email submission of homework:

QUESTION: ``On the webpage you said that we can use pine email to submit our homework by just using ^R. When I do this, a bunch of other options pop us such as Newgrps, Fcc, Lcc and I don't know what to do with them. ''

Answer (from TA Archi):
I am assuming you are using your ACF account which uses the email program called pine. Now, pine, by default uses the editor called pico. [But you can change this default editor to others that you like, such as vi or emacs.]
To start a reply under pine, you press r, with the arrow/cursor over the message you want to reply to. At that point, pine asks a bunch of question: Do you want to include the old text; do you want to reply to everyone (if the original mail was sent to more than one person).
To send a new mail, the command is c (for compose new mail). This shows a header for things like who to send the mail to, whether to cc: anyone, whether to include attachments etc., with the actual mail body visible in the lower part of the screen/terminal-window. Once you get to this message part, pico (or your editor of choice) takes over. In pico, the command to read in a text file is ^R (control-R).
So to submit the home work, press c to start a new message; fill in the necessary headers, then hit enter or the down arrow till the cursor reaches the message composition area. There you have to type ^R to include your file. In fact you can even start writing stuff, and then where you have to actually put the source code, hit ^R...
