There are currently no widgets assigned to the right-sidebar, place some! There should be 300px of available width space here.
Once you add widgets to this sidebar, this default information will go away.
You probably just installed CommPress so remember to start adding a Cast (podcast/videocast) by going
to the wp-admin (dashboard) -> Casts -> Add New.
This theme also uses the WordPress 3.0 Menu system. You probably see the default stuff you have in the menubar. Go to Appearance -> Menu in the
wp-admin (dashboard) and create a new menu.
