There are currently no widgets assigned to the left-sidebar, place some!
Once you add widgets to this sidebar, this default information will go away.
Widgets can be added by going to your dashboard (wp-admin) -> Appearance -> Widgets, drag a widget you want to see into one of the appropriate sidebars.
Boom Boom may surprise them all and have a real talent that doesn’t involve a pole or wet T-Shirts. 🙂
