Creating a Wikispaces account is rather straightforward.
  1. Go to
  2. Click "I'm a Teacher", since you are one
  3. Think up a user name and a pasword. Make sure you remember them both.
  4. Enter a valid email.
  5. Click Join.
  6. Wikispaces will take you straight to creating a wiki.
  7. Think of your wiki name that you'll put into the address. No spaces. Make sure you remember this name too.
  8. Provide additional information where needed.
  9. Make sure you have "I certify... education" checked.
  10. Click "Create"

You are all set!
