where in the forge css files do I need to change the text color so the Poll header doesn't use white text. Currently its white text on a white background which of course makes it difficult for people to tell what the polls are even about.

Other option, which may be a better option would be to change the block header background color. This of course I assume would be a css change for the right column of the page...

Nevermind, I found it

td#rightcolumn th {background-color: #FFFFFF; color: #FFFFFF; vertical-align: middle;}
