Because this course is open resource (ie book, computer, note, etc.) I would like it generally to remain closed person. The reason for this is that the amount of resources available to you are vast, and the goal here is to discover and learn the material through individual initiative.
It IS possible to help others without giving away answers.
Respond to questions with a question, give pointers to where information might be located in legitimate sources, remind them of the usefulness of manuals, and the availability of search engines.
Individuals are allowed and expected, to assist others through the mailing list and class chat WITHOUT GIVING EXPLICIT ANSWERS, so long as it does not interfere with any other existing circumstance. If groupwork is required on anything, that attribute will be specifically stated.
Explicit copying on any class work is forbidden. If any evidence or suggestion of non-authentic work is discovered in your particular direction, you risk both my wrath as well as the possibility of disciplinary action by the school. So just play it safe and make sure your work is your own.
