That's a bit misleading - Unix has just this facility. 

If you have a directory with permissions rwxrwxrwx then anyone will be
able to create and delete files in it. If you set the `sticky bit' on the
directory, then only the owner of the file, i.e. the creator of the file,
will be able to delete it. 

To set the permissions on your directory like this, use:

# chmod 1777 directory-name

This should do what you want.
