In Office 2010 Beta, the File menu contained a Share option, that allowed you to save a file directly to a SharePoint site, or even to SkyDrive.
I was looking for that option in the final release, but could not find it. Well, the Share option is no longer there, but all the functionality is under Save & Send.
It took me a while to figure that out, so I thought I might share it with you.
Did you find it? I am running into that issue now…
