This is a really useful guide if you're new to Linux and Ubuntu, even I'm discovering new stuff by reading it =)

So if you've just installed Ubuntu, wanted to install Ubuntu but don't know how, secretly wanting to install Ubuntu but not daring to take the plunge, been using Ubuntu for some time or just someone intrigued by something different from Windows and OSX, download it! It makes quite an interesting read =)
