Thanks for the hint--I've updated the node and included the link for posterity! 8^)

(Funny, though, how I automagically read the %20 as ' ', so when I entered the link in the top node, it kept giving me 404s. So then I read & reread What shortcuts can I use for linking to other information? and found an alternative: [href://?node_id=128722#the orcish maneuver|blah blah blah]. Then, in the middle of one of my "previews" of this node, I finally noticed the %20 characters, and had another D'oh moment...)
