OK, you should be able to see your homepage open with the full toolbar, and a default text box in the page. You'll be asked to edit that. When you are, please just type in something like 'I'm building my page at the moment - please come back soon' and click Apply bottom left of the Text Editor to save your changes.

So go to your homepage and carry out the instructions you see in the text box, and when you're done drag your new text to the right hand side of your page.

TIP: If you want to space lines apart like these, you currently need to click in front of the word in the line you want to drop down, then hold your shift key down and hit enter on your keyboard as many times as it takes to get it where you want it.
