OpenSUSE :: Set Default Settings For New Users?

I have about 5 users for our desktop computer, 1 adult, 3 kids and me (I don't count as an adult ).

There are some settings I want to have each of the environments default to, where they can then change them as they wish on their own.

Instead of setting them one-at-a-time, is there a way to modify the settings on the template of what goes into a user's /home directory when they are created?

Examples:
Set it so when I add a person to the system theirdefault browser is set to Firefox starting home page is to our local server Open/Libre Office defaults to MS Office formats And others, less important ones like their pictures are placed in a centralized directory, not their own ~/Pictures.

After this initial setting, they are able to change any and all of these settings on their own, but to have these as default helps me set up their environments to get them started.
