Edu clean / Edublogs Homepage

I'm using the Edublogs Homepage, which displays as Edu Clean 2.1.7

1) I am trying to change the text on the home page, where is says (in the example image) "How Edublogs can help you and your students"

2) How do you ad in the text at the top right that says (in the example image) "really easy and enjoyable to use"

3) there is also a second box next to "sign up" that says "edublogs campus..." this not part of the edu clean template. Is there a way to ad this?

4) On the demo of this template, under the HOME SIDE LEFT is a tabbed content area. How is this activate / edited?

thanks, Ted
