Everyone with a Vassar email account has access to Vspace.
With Vspace you can upload files from your computer into your Vspace account, and then be able to access them via the Internet. This is super useful. You don’t have to carry around a flash drive or burn a CD. You can work on something in your dorm or at home and then have it available in class or at the library.
A wiki is a group of web pages created and edited by one person (or a group of people) that allow for easy access and editing via a web browser. The pages contain text but they also support links and other forms of markup language.
Google Docs (which you can use for free if you get a free gmail account) allow you to create, edit, and share word processing documents and spreadsheets. They are useful for collaborating with people on campus or overseas. There are myriad academic applications.
