Dropio allows you to create an online space (with up to 100MB free) which can be shared by a group of people. There are a variety of ways to drop items into the space (web, phone, email, etc), and once items are there they can be worked on collaboratively. This is a useful tool to allow remote teams to work together.

Dropbox creates a folder on your computer, which is continuously synchronised with a personal, secure space on the web. The system gives you 2GB of online storage for free, and you can purchase more as required. This is a great way to share files online, either to the public in general, or to a selected audience. The desktop integration makes it extremely quick to use, and the fact that it works on all three major operating systems (Linux, Mac, Windows) means it can be used by all.

If you have ever found it impossible to email a large attachment, Dropbox provides a great solution.

Flickr Storm allows users to search flickr for images shared under Creative Commons licenses. Creative Commons enables and underlies a massive pool of content that is available for students to use in their projects, including images, videos and music. Whilst this site only focus on images from one Creative Commons source amongst many, it is a great way to get students thinking about licensing, sharing, intellectual property, theft, creativity and participatory culture. By encouraging students to borrow, create and then share, we teach them to value their own work, to share content without breaking the law and to create culture rather than just consume it.
