Ok this is probably a newbie question and I've tried for a couple of hours to figure this out myself but so far no luck. I'd like to qualify first of all by saying that I have been watching the umbraco.tv videos on macros. If there is some better documentation please point me there. Now for my question:

I learn by doing more than by reading so I'm going through "standard website" attempting to see how it all works. It looks to me like the 5 links across the top "Home", "About" etc are driven by RelatedLinksList.xslt. From what I'm gathering it looks through the node list for the documents under "Home". So I tried adding another one. But it doesn't show up. I cant see whats different from my new link/page than from the others. So then I deleted "Clients" and sure enough it disappears. So then I added it back, but it still doesn't show anymore. Can someone put on some kids gloves and point the newbie in the right direction.
