Banner manipulation

[ivykikoe]

Hello. My site is http://www.randompursuit.com. Right in the middle of the landing page is a banner section. 2 banners currently display on top of one another. to the right of them, is blank square of space where I have tried to insert an email signup box. Unfortunately, the signup box is aligning right and sitting a line below the 2 banners, instead of being flush them except to their right. each banner is 468x60 px, so it leaves me a decent amount of space to work with. what should I do? right now the signup box is 160 px, but the first problem I need to resolve is how to get the signup box on the same line as the other two banners.
