At No. 6 in my type Top 10 of online tools is Writeboard. Sometimes simplicity is better and Writeboard has a no-frills approach to collaborative writing. Again there is no tedious sign-up process: simply name a topic for shared writing, assign a password and identify yourself with an email address. Once the login and password is shared, users can work on the shared text without fear of over-writing because every saved version of a Writeboard document is listed, making it really easy to compare different versions. Another reason for liking Writeboard is its nostalgic approach to formatting text - take a look and you will see what I mean!
