I just signed up for Microsoft Docs at www.docs.com. This is a new service currently in Beta that works with Facebook to share documents (Word docs, Excel and Powerpoint) within the Facebook platform. They are now accepting invitations so I have been unable to use the service. Apparently you need Office 2010 to be able to upload and download files to your computer. That might be a limiting factor for many. Does anyone know if Office 2007 will be supported?
