Wouldn’t it be nice if you could access your Writer documents from any computer connected to the Internet and work with them as if they were on your local machine — especially if this could be done transparently with just a couple of mouse clicks? To be able to do this, you don’t have to install a full-blown document management solution or use a third-party file storage service. All you need is an FTP server and an OOo Basic macro.
