''' always make more then 4 pull request lets you have made only 4 pull request to different projects but one project is excluded from hackoctoberfest event then your pull request will not be count and then you have remains 3 valid pull request if these projects is not excluded. if you fail to make 4 pull request then you cant get swags or t-shirts.
i will recommend you make pull request to your own repo which is very very saffest side for you.. keep in mind that repo has hacktoberfest topic.. '''
