Alongside the need to create teaching resources, there is also the requriement for file storage that can be used to access these resources on demand. Screencast.com offers this facility. Created by TechSmith, Screencast.com provides free online hosting for screencasts, videos, images and documents. Users can control how, when and to whom their content is distributed. Definitely worth trying if you have limited storage space. A free account provides 2GB storage and 2GB monthly bandwidth or if you want more from it there is the option to pay $9.95 for 25 GB and 200GB monthly bandwidth.
