You can edit any object on your page or add new objects using your mouse. To edit existing objects, a single click will allow you to drag and resize objects, while a double click will allow you to edit the contents of the object, e.g. text.
The 'SiteMaker' toolbar at the top of the page allows you to make other changes to your site, e.g. upload your own images/files, or add new pages. The icons provide shortcuts to some of the most common features.
If you have any questions or problems, click on the 'Help' menu in the 'SiteMaker' toolbar to open our help pages. Good luck!
