I'm new to the iMac (this week) but have had some experience on *nix all though it's been a while. I've been through the man pages for chown and chgrp and can't quite figure out how to accomplish the following, or if it's even possible. I'd like to create a directory/folder that users of a specific group have read/write access to but also each user having the access to edit each others files in that directory/folder. For example, my wife and I can currently create documents in a folder I created called FamilyDocs, however I can't change any documents that she creates (were both Admins). How can I solve this? Is there a way to do this without setting up a cron job to periodically reset the permissions in a tree? Hope this makes sense. Thanks!
