Sorry, I am confused about your response.
I have already myself as an ftp user and have uploaded a temporary web page.
When I create a new ftp user, the screen says Note: New users cannot edit the files or folders of existing users!
If this is the case, how can my developer get access to my top level directory in order to load the web site?
Ideally, I would like to create an account for the developer then have the ability to enable/disable as needed.
