Hmm, I "fixed" this by making my default font size (Preferences > Advanced > Messages) 12 instead of 9. But still it's strange that when I set fonts (Preferences > Messages) they only change font style not font size...

Hey, I love this theme, but is there a reason I can't change the font size of the messages? I've seen mention of changing the stylesheet, but where would I find that? I'm new to Adium. Thanks!
