The simplest way to create a page is to modify the url in your browser:
https://wiki.jenett.org/pagename creates a new page with the name you specify.
https://wiki.jenett.org/topicname:pagename creates a new page with the topic and name you specify.
Another easy way to create a new page is to link to the page from another existing page. Note that this method creates a page in the same topic as the the page being edited. See syntax for more information.
Please stay on-topic if you create a page in an existing topic. Admin may make adjustments accordingly.
