Before and during the openSUSE conference, some nice people (Jens-Daniel, Jürgen, Darix) created the following site for you:
Thank you guys! I like the thrilling name. 😉
It’s a static page (at the moment?) and collects the current documentation from several products and projects. Probably you will see more to come in the next weeks.
Update (AJ since Thomas is ill) 2010-10-27: Based on the feedback received, we’re going to change now rtfm.opensuse.org to docs.opensuse.org. So, you can reach the fine side under http://docs.opensuse.org and http://doc.opensuse.org.
