Thank you very much for your help, I already have read this. I want to know the importance of contributors licence that the community want the people to fill before contributing. Can't this process be automated as the person have to take a print out and then send the signed copy to the community.
Also I have been working with github issues for a while so it is a little difficult to understand the ticket system and bug tracking system that the community uses. Can you please shed some light on this too.
