Barbara Bray in the PDQ (Professional Development QuickTips) column at techLEARNING writes about using Zoho Writer as a free web based word processor. From the article :

Have you ever worked on a computer that didn't have a word processor? How about using a Web-based word processor? Zoho Writer's "Online Word Processor" provides all the tools you need to write and Email your document to yourself or save it in your online document folder.

Zoho Writer not only lets you create your own documents but also allows you to share your document to collaborate with others. You give permission for your friends to read only or read and write on your document.

Thanks Barbara & techLEARNING!
