+ [2016-10-09T22:58:32Z] dataangel I forked someone else's repository, cloned it, made a change and pushed. Then when I was making the pull request I realized I made a mistake. What is the correct workflow for changing my commit? If no one else commits to my fork, should I just amend locally and force push, or is there a better way?
+ [2014-10-15T22:31:42Z] dataangel I clone'd a github repo without forking, made some branches, and committed on them. Now I want to send a pull request to the author. I fork'd on github, do I now just change the origin on my exising checkout and push?
