In my office (5 employees), I'm going to set up a shared drive, either attached to our AEBS or put inside our PowerMac. The purpose for the drive is basic--file storage/swapping that anyone can use. However, permissions is scaring me. If I create a file and drop it on the share, what do I need to do so that someone else in the office can work on the file and change it? Normally the won't be able to, since I'm the owner of the file, right? Is there an easy fix to this?
