If you have not yet discovered Google Docs, you might want to take a look at what the latest free Google tool. Google Docs (and Spreadsheets if you work with them as well) offers the following:
* Use the online editor to format documents and spell-check
* Upload Word documents, OpenOffice, RTF, HTML or text
* Download documents to your desktop as Word, PDF and in other common formats
* View your documents’ revision history and roll back to any version
* Invite others to share your documents by e-mail address.
* Edit documents online with whomever you choose
* Publish documents online or to just who you choose
* Post your documents to your blog
This is actually also a useful tool to use to back up documents. You can store up to a 1000 documents of up to 20 pages each. It’s not going to replace your normal back up systems, but is still potentially very useful. And a super useful tool is the ability to upload simply by emailing the document as an attachment to a special address Google provides you.
