Look at http://www.brainstorminc.com/products/quick-start-cards.html#Novell

They make great Quick start/Reference cards for other Novell products like Groupwise and they look very nice and are very informative and usefull.

As mentioned in another comment already: what about a Quick Start telling people where they can get what they want?

For example:
* apparmor.opensuse.org
* bugzilla.novell.com
* crashdb.opensuse.org
* education.opensuse.org
* forums.opensuse.org
* lists.opensuse.org
* lizards.opensuse.org
* news.opensuse.org
* software.opensuse.org
* http://www.opensuse.org
* zonker.opensuse.org
* …

Another example:
* How to find apparmor profiles?
* How to get updates for their distribution?
* How to get support?
* How to get the latest (KDE/GNOME/whatever) software?
* How to find/subscribe to a mailinglist?
* How to find support in the forums?
* How to become an openSUSE member?
* How to join/talk to people in IRC (channels?)?
