Apple has announced that they will be ending their iWork public beta on July 31, 2012. This means that if you are participating, you will have to pull your iWork documents before that date, or lose your documents.
iWork.com was launched alongside iCloud. iWork.com made it possible for users to share their documents easily on the site and view them on the web. This made it easier to share documents with others.
Below is the email Apple sent out:
Dear iWork.com user,
Thanks for participating in the iWork.com public beta.
Last year, we launched iCloud, a service that stores your music, photos, documents, and more and wirelessly pushes them to all your devices. Today, there are already over 40 million documents stored on iCloud by millions of iWork customers. Learn more about iCloud.
With a new way to share iWork documents between your devices using iCloud, the iWork.com public beta service will no longer be available. As of July 31, 2012, you will no longer be able to access your documents on the iWork.com site or view them on the web.
We recommend that you sign in to iWork.com before July 31, 2012, and download all your documents to your computer. For detailed instructions on how to save a copy of your documents on your computer, read this support article at Apple.com.
The iWork team
