If you're making small fixes, please do it by pushing an extra commit to your branch, instead of amending the commit and force-pushing it. This makes it easier for reviewers to see what has changed each time. When someone clicks the "squash and merge" button they will all be squashed into a single commit on the "main" branch.

(Personally I think force-push is OK *sometimes*, e.g. if you need to manually rebase on some upstream changes that cause conflicts in your patch. But it should not be used all the time.)
