EXAMPLE HELP EMAIL: OK
=======================
This email names the assignment and describes the general problem, which is a real improvement.
However, it still leaves out important details: what specifically is not working, what has
already been tried, and what the error or result actually looks like.
The reader knows more than in the poor example but still cannot help without asking follow-up questions.

Subject: Question about the Linux lab

Hi Professor,

I am having trouble with the Linux lab that is due tonight. I have been trying to get
the file permissions part to work but it is not doing what I expect.

Can you help me figure out what I am doing wrong?

Thanks,
Sam
