I have been working on a report concerning a Katrina survivors listening project and several people need to feed input into this report.   I found and online word processor called Zohowriter which allows multiple users to update the same document from any location they happen to be at.   I could go to the library and update it from one of the  libraries computers.   I gave access to someone else to update the report and she did a lot of the work from her house.    It was working great until yesterday when it would not seem to save any of the changes I was making but today it  is working fine.   This  is a free service, you don't need to download any software to your own  computer to use it.     What I don't know is how they fund it.   I don't see any advertisements that usually show up on the free services.    Is it all volunteer time?   If it is, they don't seem be be asking for donations like a lot of the shareware developers  do.    Anyway, it seems to be a great service and I highly recommend  it.
