The Windows Live team announced some changes to the SkyDrive beta today.
Among the changes are an increase of space for users from 500 MB to 1 GB. Also, being that you can have a public folder that is read and write for other users, they have incorporated an RSS feed feature that allows you to track changes to your public folders. In other words, get notified when a new file is placed in the public folder including who put it there.
Windows Live SkyDrive allows you to store and share files online, for password-protected access from anywhere. Simply associate your Passport account and have access to your data from anywhere. A handy tool for sharing files between home and work.
