Hi Jeremy

Yes, but that would mean editing each page where I want it, and being
worried about it if I change the length of the page. I wanted
something that would, if I added an extra paragraph that took it
overlong, add the link automatically. Goal: easy life.

Actually, I started making a footerBig version of the footer which
would have required me to insert the former rather than the latter if
the file became big, but the problems the same, which is why I wrote
to you nice ppl.

What's more, I'm going to do it again, ha ha!
