To create a new page on this wiki, just create a hyperlink to a non-existing page. Then select that link, and you get an option to create and edit that page.
So, first, select your group project in the group text, then add a link (if you're using the rich editor, highlight the word and select the link-symbol on the tool-bar). Call the link for example 'project', but instead use a page-name which is more specific to your group (since there can be only one of each page).
