This URL shortening service is no longer available.
We're always working to give schools what they need, including the ability to allow or block URL shorteners. In a recent update to our database we moved URL shorteners to their own category to make that even easier. If you wish to use a URL shortener, many other safe options are available and we encourage you to explore them. Don't worry: existing mbcurl.me and lsurl.me shortened URLs will continue to function.
