what is C#Corner Member of month, MVP ,Speaker and Chapter Lead .

Question

Hii,

I am curious to know how anyone achieves these achievements 

1. Member of Month (I think in 2020 it is closed as no one is showing in lits) 
2. MVP (perhaps quarterly announced)
3. Chapter Lead (perhaps huge points or knowledge required)
4. Speaker (ultra Legend I think)

What are these and how I can be any of them?
