Changing default group for old and new users

[tyreth]

Anyone have an idea how I can change the default group that new files for a user are created under? The default for gentoo was all files to be in the group users. I want to set it up like other distro's that have a group that is the same as the users' name.

Or, perhaps, that files are created default with no permissions for the group. I have having everything in my home directory created as world readable by default.

So I guess I'm looking for ways to change:
a) when any user creates a file it uses the group named after the user and not the group users
b) new users automatically have a group named after them created.

Any ideas or alternatives, I'd love to hear thanks.

I did a search for this topic, but couldn't see anything - could be my poor search skills.

Woops, I hate it when i ask a question I know the answer to - the passwd file contains default group

Thanks for the /etc/profile hint for umask, thought that umask might be the way to go. umask 077 gives me perms I'm happy with.

So yeah, thanks
