There's a extreme answer... But maybe not a popular one and a massive no go minus manz, you could gut and delete the entire contents, replace the pinned and top posts... It's been dead for months.

Reuse the old frame for star wars Persiant world. 

Drop the entire starwars into the old one and empty it.

You could hide them all. And maybe put them back later into a new format once Manz returns.
