What is eMood?

I have never heard of 'eMood' as a grammar term. Perhaps 'mood' is meant. Your sentence is one form of imperative mood.

so my next question becomes "how many forms of Imperative mood are there"?

I only know two: first person ('Let us') and second person (understood 'you');

Let us go to the circus.
(You) Eat all your broccoli.

Can you give some more examples of second person? thanks

and another thing in the above sentence I used "some more examples" is that right?or it should be "some more example"?because I used some for plurals. thanks again for your kind time and effort.

Some more examples is right.

2nd person looks the same, whether it is a command, a request, advice or an invitation:

Remove your shoes.
Watch out for that bicycle!
Please pass the salt.
