The question title sounds vague, but it's a wide topic and I'm unable to give a clear title otherwise.
So here's the background info and question:
I'm quite a new user to Ask Ubuntu and I've been trying as much as I can to help others around me, however I've found when answering questions that I seem to be limited in my knowledge (mainly due to the fact that I've only being using Ubuntu since Oneiric). As such lots of questions to me seem unanswerable, or at least I can't give a complete answer because I haven't had the same problems myself. So to summarise, I'd like to know if there was a way to learn the basics of Ubuntu without stumbling accross forum posts and the internet pointlessly noting things down and trying them out?
I stumbled across this question and looking at the available course given in the answers I wanted to know if any of the following existed already and if they do where I could find them? :
An online explanatory course with step by step Ubuntu learning such as the one offerred by Ubuntu which gives you knowledge of everything related to Ubuntu ranging from networking to unity specific commands (it doesn't have to be recognised by Ubuntu for certification, I'd just like to learn that's all)
Guides about networking, server management, apps, etc through Ubuntu. Is there a site which keeps all these guides in one place so I can read through them?
A site dedicated to learning everything Ubuntu-related where specific topics are discussed on certain days or at certain times and people can join in whenever, where there is a hierarchy in the courses:
eg. Using the Command Line Interface-Beginners "What is sudo/ls/cd and how do I use them?"
