<h3>Step One: <span style="text-decoration: line-through">Steal Underpants</span> <a href="http://usemod.com/cgi-bin/wiki.pl">UseModWiki</a></h3>
<ul>
  <li>We used UseMod for "Grubstreet", our original London wiki.</li>
  <li>It was good and bad.
  <dl>
    <dt>Upside:</dt>
      <dd>One script, 30-second installation. Nice.</dd>
    <dt>Downsides:</dt>
      <dd>4,000 lines of dense "Perl 4 stylee" spaghetti code. Hacking on it makes your skull glow white-hot.</dd>
      <dd>Weird recurring problem with file locking.</dd>
      <dd>Basic wiki functionality wasn't enough for our requirements.</dd>
  </dl></li>
  <li>So we wrote our own.</li>
