Please do not post new problems to me personally this way.
This forum does not work this way.
Post new problems to the forum ONLY through the specially created web-page for these purposes.
The comment window (so called "Thank you form") serves for totally different purposes.
When you post new problem to a tutor through this "Thank you" window,
it is the same as if you drive on a highway using the reverse transmission.
Have a nice day / night / morning / evening / afternoon and the tea time (!)
