Title Align and contact form message

I have a question, why in "About us" ("Sobre Nós" in portuguese) the Title of the article is center and in all of the others articles are align in left?

Other article: http://www.esportesdeaaz.com.br/modelo2 ... em/388-nba
How can I fix this?

Another question is about the contact form. Need I configure something? I used the form to send a teste message but the message never arrive to me.

Hi

Both Your links are showing 404 error "Not Found".

For contact form You may need to configure SMTP in global joomla configuration since some servers restricts using the standard mail() function.
