You haven't caused any issues at all J, the tutor posted the code himself in another thread and that was my point, even non members could use it which was also my point, you are a member here so you are perfectly entitled to the discount and the use of the code, so don't worry mate you've done nothing wrong.
I apologise if I made you uncomfortable, I should probably have made my point in Tutors original thread or even PM'd him, so it's my bad (again)
