- Automatic email notification. Now the iWork.com beta lets you stay up to date whenever viewers add new comments or notes to your posted documents. You can choose to be notified immediately, hourly, or daily.
- Enhanced security. Automatic 128-bit SSL encryption now safeguards communication between you and your viewers via iWork.com. You can also password-protect documents you share on iWork.com-so even if someone has a link to your document, they won't be able to view it without the password you supply.
- Refined user interface. The redesigned Shared Documents page includes thumbnail previews so you can more easily identify your shared iWork files. You can also organize your shared documents by date, name, size, or comments received. And you can now access all your shared documents by signing in at www.iwork.com.
You should be able to use these new improvements once you've updated to the latest version of iWork '09, if you haven't already done so.
Also, Apple has set up a new iWork.com news page, where you can get updates on iWork and the iWork.com service.
Hopefully, these improvements will further advance the iWork.com service.
