I have a small network that includes 3 Macs, all with different OSes (Panther, Tiger, Leopard). The Panther system is set up to share the public folder for everyone on the network. I'm not concerned about security in this folder, I want every file to have read/write for everyone. So far this hasn't happened. Whenever a new file is saved or transferred from a different computer, the Panther system can't write to it. How can I change the folder so that every file is automatically given the full read/write permissions?
