Greg, Wendy and all,

         This checkpoint hits me square in the knees! I've mentioned my 
little fiefdom of interrelated sites, located on 3-4 different servers. The 
sites interlink among the servers as needed, but I have only one navigation 
scheme - namely links to other sections or pages, and links to outside 
sites.  Checkpoint 2.1 should help me decide what steps to take to increase 
the navigation of my sites (either individually, or collectively), but it 
should also address those who are planning a complex site from the git-go, 
and need to consider this at the beginning, not after they grow an octopus.

         Greg said that all sites provide at least one site navigation 
mechanism, but I wonder -- if a page (on a site or the only page on a site) 
has no links except to outside content (or is just content itself), what 
navigation mechanism is going on. I often make pages that are the "leaves" 
of the trees, which do not link to any other pages on the site, and the 
user must use the Back key to navigate backwards on the site ...

         I think I'm suggesting that telling folks to put at least one 
navigation mechanism on a site, and add navigational mechanism as the 
complexity of the site increases, would provide information to the hacks 
like me who grow pages willy-nilly to meet this or that need or 
inspiration, as well as provide guidance for those who plan complex sites.

         Would it be considered "part of a navigation mechanism", if at the 
bottom of all pages within a site, there was a link to the homepage of that 
site?  Would that constitute a "navigation mechanism". Is there a second 
"navigation mechanism" on the homepage that generally links to all the 
sub-pages? Suppose the homepage only links to a sub layer, (perhaps four or 
five pages), and the actual content is on the links from that sub-layer of 
pages. If the "layer" mechanism is used, is an index page then called for 
(I don't see the need for an index page if the front page lists all the 
pages on the site.). At some time, a search feature is necessary, but is it 
when a site grows to two pages, or ten pages, or 100 pages, or is that 

         Wendy, your comments that 2.1 may need to be structured similarly 
to 3.4 to provide a wide range of possibilities and techniques, and trust 
the author or site designer to pick what suits the site in question best, 
is excellent. And I agree.
