Skydrive and Office, Live
Users of Microsoft's Live service now have the Redmond firm's answer to Google docs available to them. Visit http://office.live.com
and you can access Skydrive, an online cloud-based service allowing you to store documents and access the web-based 2010 versions of Word, Powerpoint, Excel and OneNote.
The service is free to use and requires a Windows Live Passport login. Testing today did reveal LA filtering succesfully blocking the social media aspects of the Live service while still allowing the documents feature to work (though SkyDrive itself may be classed as Open Resource Sharing for some LAs).
