a question about pier syntax

First a quick note of thanks. I am really enjoying using Mobile Wiki Server. I also like that I can edit from my desktop. I have read your site and been digging around piercms.com as well. I was hoping you could help with two questions: 1) I have tried using Breadcrumb but I cant get it to display in a page or even in the overall structure (Using the design button). How do I use this command? Basically I would love to have a breadcrumb showing me where I am in the hiearchy of the site. Example: Home > Grammar > Nouns > Examples this would allow me to quickly move back up the hiearchy. 2) I like the tree and navigation components. Is it impossible to embed this into a page? I would like to have a page with some basic content and then have a tree structure listed below. However, it seems i have to add a component page, set it to tree, and thats all i can do with it. Thanks for your patience with me. Again I thank you for bringing this to the iPhone. Chris
