I have a spreadsheet that I would like people in my group to be able to
access, edit and save on the web.  Is this possible?  I'm not talking
about downloading, editing and uploading.  I'm talking about opening a
file/spreadsheet on the web, putting some information on it, 'saving'
and then the next person that works on it will start with the previous
changes made.

I looked at some file storing sites - efiles, box.net - but you
couldn't open the files and work on them while on the web.  You had to
download, edit and upload.

Does anybody know if this can be done, and where I can look?

I really appreciate any help.

Thanks,
John Davis
