How can I change the "about me" section?

To change the About Me section that appears on your page, it is in a
box. By default, it is directly below your activities (comments you’ve
made, or have been made on your page, forum activity, etc). To change
this section, click the edit button on the top right of this section.
A text window will appear and you can add text, photos, links or html
code. To save the contents of this section, there is a “save” button
at the bottom of the section. Some folks have tried to change this
section by going to the “about me” section in my settings. That will
have no affect on the written content of your page. You can also
change the title 'My page' to something different...hover over the
text until it changes color then click on it. Change the text to what
you want then click 'save'.
