&gt; Do not hesitate to make it clear that that&#x27;s not the place for such behaviour<p>Perhaps the point (of the cowboy image, perhaps with regards to self reliance) is that you can tell them that you decide, since you started the project and are still its leader, and that since you think the contribution is screwed up, you won&#x27;t merge it. This explanation does not contain anything about the contributor&#x27;s behaviour. Well I guess I don&#x27;t know about what that part of your example entailed :)<p>Anyway, thanks for the comment!
