Please fill in who you are - are you a student or a teacher/lecturer? Where do you use Newt, and what do you use it for? What are you studying/teaching, and where? If you have an email address, fill it in so that we can get back to you with a solution or explanation (or grateful thanks!).
If you want to report a bug, tell us as much as you can about what you were doing when you encountered the problem, as this can help us to fix the bug and improve Newt. The order in which you did things, and anything you may have been trying to plot will help us to reconstruct what went wrong.
Be honest - we want to know!
