This is a neat idea, I went ahead and set up a page at /home/moondog8/scatterwiki/moondog8.html
I cross-linked to your page at /home/cmccabe/scatterWiki/index.html - I had to use the 'file://' URL protocol in the link, as a direct path caused Lynx to treat it like an FTP link.
I already find myself wishing I could use some flavor of wiki markup instead of HTML, though. Not to propose more work for the admins, but I wonder if there are any simple Wikis out there that play nicely with Lynx, and could be configured to listen only on localhost. I'm not even sure it would be necessary to try and integrate user accounts; the earliest wikis I remember were deliberately simplistic in that regard; some would provide an author/editor field, but it would be as malleable as the rest of the wiki.
