FTP directory management

Hi Guys

I create project based ftp accounts at various levels and can control hapily the process but one thing I never managed to do is to have a shared directory in a project group. Typically 5 guys will deliver work through their dedicated lump of ftp accessible server with each to their own, but they get their instructions through a common shared project directory.

The what I do now is put a shared directory in each of their accounts and copy files into it. which is just not write.

I have read around the web for info but have never quite managed to find an artical that defines a process I am looking for.

Can anyone tell me how or where to read up on a method to achieve this?

Many thanks in anticipation.

Brian
