I prefer that you hand in your homework in class.
However, when this is not possible follow the instructions below to have it accepted via email.
Homework sent via email must use Microsoft Office tools.
Be sure to include your name on each page. Often the pages get separated in printing.
To ensure your homework is accepted, title your attachment as follows:
"letter letter last-name" space "HMWK" number.
Example: EDBenson HMWK3.doc Please be consistent with your name so I don't have to guess who it is.
Expect a simple reply like "received" or "OK" from homework submissions.
The reply is sent when the homework file is processed, not when it arrives in my email box.
Same day service should not be expected - although sometimes it happens.
If you need an answer to something before class, send email prior to the day  
of the class.
