I created a new test page to see how the new page would connect to the front page, but I can't find it now. Where did it go?

Jeff, you should be able to see your test page by clicking on "Show all pages" on your wiki at the bottom of the page. You can link it to the front page by editing the front page and adding a link to your test page (Click on the Edit link, then click on the "Link" button, then select your test page from the drop down menu)
