Easy:
  1. Make sure you are signed in to wikispaces.
  2. Go to www.wikispaces.com (the main page for wikispaces, rather than our wiscwiki site.
  3. In the top left corner of the screen, under the word "actions" you'll see a link to "Make a New Space."
  4. Choose a name for the wiki.
  5. Choose whether you want the site to be completely public (anyone can edit), protected (anyone can view, only members can edit), or private (only members can view/edit).
