I’m quite decided about that…
Anyway, do you know what i need to write official editorials??
Qualification and all??
I think you need to be a part of the problem setting team or the individual who submitted the problem . Don’t know much though .
Oh okay…
Thanks 
May consider Aadhar card or green card, passport or any other unique id as per country… but quite complicated i guess
@taran_1407 - Only good english is needed to apply for Editorial writing. You can apply for that if you want. Being part of problem setting team is not a compulsion.
And what if i don’t know solution to all problems of a set, say SEPT Cook Off??
I knew solution of only three problems…
What would i do in that case???
That’s what i really wanted to know…
And…
I won’t mind testing problems (but i don’t have any account, on SPOJ, codeforces and all… I’m only on codechef, neither the experience of testing problems…)
