Ok, sir changing the topic name. Happy now?
Nope i am not asking to rechange it 

I’ve changed it already.
my idea is much better to change the name to some random title and flag it too. 
Shef will sometimes cheat: he can change his prime any number of times during the game (even after you tell him your guess), but only in such a way that all his answers to your previous questions remain correct.
I didn’t get this. Help me!

Happy now ?

We replied most (probably all) relevant questions. I didn’t replied @mkitkat question because I considered that the line “but only in such a way that all his answers to your previous questions remain correct” is very clear.
I think if the panel can reply “No Comments” to such comments (like in Codeforces) it’ll prevent a lot of them from asking it in forums.
Helps to clear the misconception that setters do not reply to doubts/comments.
Agree on “you reply to relevant comments” 
I appreciate that 
Yup I wanted to suggest this here but then I didn’t. It would be great if cc can do something like that as well.
Such a nice contest, had a fun while solving these question and very well balanced also.
