Too often when working with someone else on something we fall into the trap of endless revisions of a document being emailed back and forth. Usually you inadvertently grab an older copy at some stage and lose a complete set of edits! Google Docs is a totally free online solution!

Google Docs allows you to create and edit (and quickly import your existing) documents, spreadsheets and presentations. All you need is a Web browser, your documents are stored securely online. This means that you can access and edit them from anywhere, and invite people to your documents and make changes together, at the same time, in real time. In addition to working with documents and spreadsheets, you can now collaborate on presentations and share them in real time too.
