Things are getting worse.... until now, they posted here one assignment
(without "hello", without "please", without "thanks in advance")...
Now they post the whole list!!!!
A day will come that they will post direct from the classroom: "hey people,
I am doing my examination, i need the answers, NOW!"
Maybe we should change the name of the list: "WE WON'T DO YOUR HOMEWORK -
C-PROG"
Best regards!

"Que o caminho seja brando aos teus pés;
Que o vento sopre leve em teus ombros;
Que o Sol brilhe cálido em tuas faces;
Que as chuvas caiam serenas em teus campos.
E, até que eu de novo te veja,
que a Deusa te guarde na palma da mão! "
