OK, add this to your custom CSS:

@media screen and (min-width: 980px) { /* This is the width of the forum content area */ .bbpress #content { max-width: 95%; } /* This is the width of the forum list */ .bbpress #primary { width: 66.6666%; } /* This is the width of the forum list */ .bbpress #secondary { width: 33.3333%; }
}

So this is a media query that kicks in at screen widths above 980px. Inside the media query are three rules. The first changes the main content area from a max width of 980px to 95%, so the content area will expand as the browser window expands.

The second and third rules sets the width of the forum list and the sidebar. The widths are what is currently in effect, so the forum list takes up about 2/3 of the space, the sidebar takes up 1/3. You probably don't need to change those unless you want to give more space to the forum listing, but make sure the widths add up to 100%. You can try setting the forum list to 75% and the sidebar to 25%, for example.
