It was my brother who told me, that he still couldn't see the howto's on my site. So I figured out that making your Google Docs visible using a link isn't enough. You really need to make them public. Oh Well, no problem. I just might put some comment on top of each howto, telling you should check out my website, because now my Docs are web published en searchable in Google itself. Thanks Bro. for telling me.
