User Dashboard is blank in main frame area. How can I add content to this?

When a user logs into their account, the options they see are only to the left menu in WordPress. I used the clean up plugin to get rid of the WP fluff, but would like to show my own content in the Dashboard area that at this point is just dotted blank squares… Please see my image for idea of what I mean… http://www.wpmarketingsuite.com/wpmu_user_dash.jpg

Is it possible for me as admin to set up what is shown to members / users once they are logged in to my site.

Thanks

PS: NOT a multisite install, only standard install, using the Business Services Theme and the Membership Plugin.
