Strange!

@astrojuanlu you said in the comments that whosoever wants to work on it. Thats why i mentioned it. If @iamabhishek0 wants to work on it i dont have any problem regarding that. All yours @iamabhishek0

@priyanshurohilla There is no need to announce you are working on a particular issue. On one hand, we see a pattern of people making the announcement and then never sending a pull request, which gives a bad impression (I have been guilty of this in other projects, and it still is not a nice thing to do). On the other hand, it gives the impression that others should refrain to work on the issue, which is wrong.

And finally, as @iamabhishek0 correctly points out, he did the investigation, probably already has some progress, and you announced you were working in other issue.

This is not a competition folks. Thanks for your enthusiasm!
