How to create shared folder by default

Question

Hi
I have a problem of course. I want to create new folder in my shared folders with the same permissions as the "root" folder. It doesn't work! Why?
Everytime I create a new folder it gets limited permissions for Groups and Others.
Please ...

As you have discovered, any new file created on OS X is read-only to all but the creator.
Fortunately, OS X 10.4 has a feature called Access Control Lists that will allow you to create a shared folder in which all files will automatically be read+write for all the users you specify.
Log in as an administrator and create a new folder in /Users/Shared called "sharefolder" or something similar. Then, from Terminal, enter the following to enable ACLs on your boot drive:
sudo fsaclctl -p / -e
Then enter this, replacing USERNAME with the short user name of the user to be given access (you can paste the whole thing at once) :
sudo chmod +a "USERNAME allow delete,chown,list,search,add_file,\
addsubdirectory,delete_child,file_inherit,directoryinherit" \
/Users/Shared/sharefolder
Repeat that last step, replacing USERNAME with the short user name of another user to be given access.
When you are done, all users who you specified will have full read/write access to everything that is placed inside sharefolder in the future. ACLs are one of Tiger's most underrated features, IMO.
Warning: Files have to either be CREATED in the folder, or COPIED there. MOVING files from elsewhere on the same volume to the sharefolder won't cause the new permissions settings to stick.
