BP - Corporate - how to create another page submodel

Hi !

Me again...

Well I have solved all my pbolem and we decided tu finally use budypress and Corporate theme.

Install : WPMU 2.9.2, BP 1.2.3 with theme BB corporate.

What I need to do :

- Create, like in other themes template, a "full widht" template page to use in my corporate theme, wich i can use in creating new pages. So a template just removing sidebar

I looked around in manuals and WP help but did not really find an "how to"

Where can i find the process to do that ?
