Features / Usability

Hi.
I want to set the width of two modules i use on my front page. The modules are Last blog posts and last articles. I show them on my front page using wiki pluginmodule.
The problem is that the modules exceeds my pagewidth on the right hand side, wich looks kinda stupid. I can not find any parameters i wikisyntax so i hope somone here can help me.
My page is http://fjot.org if you want to see what it looks like right now.
I would apcreciate it if someone has an idea on how to solve this.
PS: I tried to use tables to limit the size, but it would still exceed the table border in the same way it now exceeds the page border.
