Thank you for contacting us.
You can change your message by clicking on Page 2 in the directory tree on the left-hand side of the screen. Then in the properties on the right hand side, click on the EDIT link beside the word "Intro," which will take you into the text editor to make changes.
(You can add text to sections in the same way. The only difference is that the word to the left of the EDIT link says "Description" instead of "Intro.")
