I have a question for the list about the homework rule and the tutoring
list.  If you have a question and you're not asking for your homework or
past homework to be done for you but you just have questions to be explained
isn't that what tutoring and learning is all about.  For example, on my
question here.  I have a problem that is not homework for a grade and I
don't understand it.  I can't find a tutor.  I'm frustrated and you guys can
provide help for my understanding which you were doing.  Not by giving me an
answer, but by asking me questions and helping me to understand.  Isn't that
what tutoring and open forum is all about.  Unfortunately, I still don't
quite have it I feel like I got left hanging on the edge of almost...

I called the Dean of Graduate students at NC State to try to find someone to
tutor me and the response was helpful but Python isn't taught at NC State.
UNC - the same.  Wake Technical - the same.  I've looked on Craig's list and
Googled with no luck  I'm taking an intro to computer science class online
through Utica for Cybersecurity and I would just like some help
understanding.  I'm not one to easily give up!!

Anyway, I understand having rules and why, but I also think that when those
rules don't make sense under the situation exceptions should be made.  Just
