Settings - URL shorteners

­­­­­­­­­­­­­­On this tab, you can adjust settings related to URL shortening services that can be set for Facebook, LinkedIn and Twitter. Such services shorten URLs that are undesirably long in posts. It is especially useful in case of Twitter, because its posts cannot be longer than 140 characters and generated URLs can take up a lot of this space.
