A tutorial isn't really the same as a manual though; though I realise he did say in his thread title 'manual' as well.
Believe me, a manual is fine for someone who has familiarity with the subject matter, or the more astute. But they are useless for many users. At my job I find myself often putting into plain, understandable, memorable English manuals by big manufacturers and suppliers. This isn't to say a manual isn't helpful, afterall you would expect it in most ways to answer all of your questions. But a tutorial is a much more engaging, and the key to succesful learning is engagement.
But anyway, sorry OP but personally I don't know of any tutorials.
