Intel or AMD?  (Btw, it wasn't exactly obvious, my brain was hurting after
thinking through that stuff:-)

You mean that <<!!RatsAndMice>> should work the same as
	(:trails !!RatsAndMice:).

Guess you'd expect that, but I still think the latter is easier to read...

Um... *thinking* .. with
	(:trails !!RatsAndMice:)
don't you mean that if the current page is listed on a *trail page* that 
belongs to the category RatsAndMice we'll get trail links?

It's when you use
	(:trails !RatsAndMice:)
that we'll get a trail link when the current page is listed on the page 
Category.RatsAndMice (i.e. the current page belongs to this category).

A very good idea, give me the links when you'd like me to read it.. I 
suspect we'll have to iterate through the them a few times before we've 
gotten all the details right...
