Page is created, but not linked on main page

Hi all,
I’m working with theme benevolence. I switched permalinks on, everything works great. I’m trying to include an about page. After I create it, I can see it at http://www.miamidrums.com/about/ but It doesn’t get listed under the main page.
I’m not completely sure what I’m missing…
Could it be that the theme is not including pages?!

Regards
