Open a new blank document and follow these instructions from Pages Help: To create an alignment guide: - Click View in the toolbar, and then choose Show Rulers. - Place the pointer over a ruler, click, and drag onto the page. An alignment guide appears. - Drag the guide where you want it on the page. Does this work for you?! I just get a cloud and, when I click-off, the cloud disappears. I cannot work out how the hell to get an alignment guide.
