Changing font size in sidebar? Need help

Hey guys, I installed this wordpress theme

http://themes.wordpress.net/testrun/ which you can download here: http://themes.wordpress.net/download.php?theme=1411

The font size is great on the sidebar until I try to add my own links under the meta green bar. The font for my links is smaller than the rest of the font already there. How do I change this. I checked the style sheet for a .meta tag but didn’t see it. What do I need to change? Thanks!
