I like helping newbies. I guess that’s why I like teaching too 🙂 It certainly makes you think, especially explaining things via email, making sure that you cover as much info as possible without waffling off topic or being too confusing. It’s good practice for teaching too.
This is a good introduction to Linux for beginners and it covers a lot of information.
Another good thing to have is the One Page Linux Manual which I think I’ve posted about before.
Here it is One Page Linux Manual complete with a link in the comments to another helpful site.
