Everyone has a Google Account, but just in case, if you do not have a Google account, the company has just launched a new site for anyone who wants to try Google Docs can do so without having an account. The exact address would docs.google.com/demo.
From this new move Google aims to capture as many users as possible and compete more strongly with Microsoft Office.
On opening the demo site, we would find a document that will give us some guidelines on how to start writing with Google docs. What needs to be clear is that there is an option to share or collaborate with others in Real time. The document would be available for 24 hours after its creation.
The new document comes with a link that enables you to invite others to collaborate on the issue (these users will NOT be invited to have a Google account).
