BuddyPress.org

I’m running buddypress default 1.6.1. with courseware 0.9.7 installed.
The space hungry side bar with the login on the right is commanding the page on smaller screens.
My main window uses “anythingslider for wordpress” to house embedded videos.
This window is squashed to a thin sliver on the left, leaving the rest of space to be either shared by the right sidebar and the ‘lecture meta’ second sidebar, or it drops the rightsidebar to the bottom and leaves me with just the ‘lecture meta’ second sidebar dominating the screen.

I’d like to have the main window filling the space, and drop both these sidebars to the bottom of the screen, both in mobile view and web view.

Is this possible?

Thanks in advance
