It’s not too big of a deal, honestly. In order to continue down a path that makes sense, Microsoft aptly renamed the Office Web Apps division of products to Office Online, because naturally, it’s Microsoft Office — just online.

That being said, get those agreements typed out; I need them by 3PM, sharp.
