In particular:
  1. Page is linked from another TWiki page - this is natural if you create a page by introducing a new link on a page and then create the page by clicking on "?". Do NOT create pages in other ways - else the parent (listed at top of page) will be WebPreferences, which is not correct.
  2. Page name must be a WikiWord of the form

    • Additional lowercase or uppercase letter(s) or numbers are optional and may follow in any order.
    • Underscore "_" and Dash "-" are not valid in the name
  3. Pages must have an appropriate Metadata Parent - if you don't understand what this means, look at the ATLAS Twiki Rules.
