Re: Adding new pages... how?
Maybe it's not clear if it's your first time editing a wiki but, as far as I know, the standard way to make a new wiki page (not just in Tiki) is to edit an existing page, adding the syntax for a link to the new page, and saving. When it refreshes, the edited page will show your link followed by a question mark that indicates it's a link to a page that doesn't (yet) exist. Click this question mark, and you're off to edit the new page.
This is detailed on http://doc.tikiwiki.org/tiki-index.php?page=Using+Wiki+Pages#Creating_a_Wiki_Page
, which incidentally, was pretty easy to find using Google.
There are other ways to make new wiki pages in Tiki, such as the Quick-edit module, by creating a wiki structure, by typing into the browser address bar a URL like "tiki-editpage.php?page=Name of my new page" and so on. I use the last one the most.
