How are we supposed to submit the solution? The time is of course too short to enter it manually. I am getting very strange results when submitting the solution via a Java programm as a GET request ... sometimes the result is just a plain new view of the challenge, sometimes I get the error "There has been no question asked to you.". Once I got a "Your answer is correct", but it turned out I had been logged out automatically just before, so of course this did not count.
