PasteLink is a simple to use tool that allows teachers and students to send large files (up to 250MB) without having to sign up and register for a service. Users can also share as many files as they want and they will stay accessible to the other party for a full week. This is a great site that breaks the 10MB email cap that most schools enforce and it is simple to use with its drag-and-drop file loading and no registration requirement. A great way to quickly and easily send a large video or photo file that otherwise might require a service with a registration or a physical media exchange.
