How to separate adsense blocks?

[NoPretender]

On my forum index I want to put two adsense blocks below the "Who's Online" box. I don't want them right next to eachother but I would like them to both be centered and spaced about an inch or so.

Can someone tell me how I can do this?

<div align="center">ADSENSECODE &nbsp;&nbsp;&nbsp;&nbsp; ADSENSECODE</div>
