Hidden edit mode link
When a template is created, an edit link is placed on the page, typically by using a small 
icon. The template designer may chhose to make the link hidden by using an existing graphic, or by using a text link that is the same color as the background. Since it is part of the template, this link is available on any page within the website. For the default template on Contentor.net, the link is in the upper right corner of the page.
If you cannot find the link, you can also enter edit mode by editing the address in the browser's 'Address' bar, changing the portion that reads 'index' to 'edit' (the home page may not say 'index' until after clicking on a 'home' link).
