I'm sorry, I guess I wasn't clear. The link provided is pretty obvious in terms of usage, but where did ww get the link in the first place?
For an unrelated but similar example, consider me looking for history on the Chatterbox. The other day I realized that the link I had for CB history was dead (the nbpfaus.net link). I was given another link: last hour of cb. This works really well, but where did the link come from? Tribal knowledge? Random guesswork on node numbers? Leprechauns? In that example, if you click on Other CB Clients, at the bottom of the page is a link to Chatterbox FAQ, which has a link to last hour of cb.
That chain of links (or something similar) is what I'm asking about here. The link to Corion's site came from somewhere, I just don't know where.
