Maybe I am pedantic now, but what you describe here as WikiTrail is
what I would call an index page, which holds a list of page links.
A WikiTrail requires the trail markup in each page, and so is not
defined just from one central page. The trail markup also provides a
link back to the trail page, much like when using categories. So a
WikiTrail lies in between index page and category. To add page XYZ
into a trail, we create a link from the trail page to XYZ, and we
create a link from XYZ back to the trail page using trail markup
<<|trailpage|>> or variants of it.
Thanks about explaining the use of categories, and introducing and
encouraging the use on pmwiki.org! It will be very useful indeed.
