The review widget is where you ask for a change on your website and tie it to work you already approved. The page is not built yet, so it shows page not found. Type what should change: make the main button read See workshop details. Keep the rest, and do not publish. Click Add. The toolbar now shows one unsent request. Then scroll the panel down to Approved work link. Paste the link to the website task and click Check link. The line below reads Checked: B, Website build. That line names the website task, so your request is tied to the approved work. Click Send once. The panel changes from the old red Failed to Working on it. The panel shows your last request's result until you send a new one. A new request starts fresh. About forty minutes later, the preview is ready. The panel says Preview ready, and the page now has a See workshop details button. Your change was requested and you can see it in a preview. Your live page has not changed.
