Click the _Edit_ text above, in the line next to "Search". An edit window will open, with this text in it. Move the mouse pointer (I shaped bar) to a blank line after these lines, and type in your first and last name, like this:
Then hit the PREVIEW button. You will see this text appear above the edit box. Click YourName among that text, and another editable text box will appear. You can type in your information, no indents, with paragraphs indicated by two carriage returns (ENTER key).
See how it looks with the PREVIEW button. When you are happy with what you wrote (or give up) click the SAVE button. I will see the changes at some point and fix your page for you.
Don't worry if you mess up, I can always put things back.
