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.
When you select an object, the 'Editor' will display a number of panels which allow you to change settings on that object, e.g. for text this could be it's position on the page, e.g. 'Info' tab, or the font that you use, e.g. 'Font' tab. Different objects will have different settings.
To view your site as visitors would see it, click 'View my site' in the top right hand corner of the site. To get back to edit mode, click 'edit my site' in the floating edit panel (your visitors won't see this panel, only you can see it).
If you have any questions or problems, click on the 'Help' menu in the 'Toolbar' to open our help pages. Good luck!
