Forum:How do I get the columns on the mainpage to display properly?

There are two columns on the mainpage I have, and the right one displays all the way at the extreme right side. How do I fix this and get it closer to the middle?

Here is the exact same thing as the mainpage, only it is unprotected. http://sturmkreig.wikia.com/wiki/User:Sascha_Kreiger/Sandbox/New_Main_Page
