Change case of menu text

Hi everyone,

i'm using the daily theme and need to change the menu text from "forced caps" to mixed. i've got a couple links that won't look right in all caps, it'll make it read weird. for instance: ListYes vs LISTYES. (i'm talking about the main, tiered menu system on the homepage of the theme, immediately under the header)

seems simple enough, but any help with which file and/or location of the necessary change would be awesome!

Thanks!
Jason
