hey,
guide looks good (content wise) but i don't get all tables displayed well, could you use "&nbsp" in the empty fields so that all the borders are rendered well.
you'll see that the "&nbsp" works as an invisible space
(might be "" been a while since i did websites )

otherwise great work, thanks a bunch

[edit]taking time and liberty to add what i meant to say, if the desired effect is not to your liking, feel free to revert the changes
