To Edit that font will also edit all the font on the majority of the post form. If you choose to edit it you can do so in Ripple/forums/forums.css (line 118)

.gen,.genmed,.gensmall {
color: #28313C;
}

I would prefer to alter the colour of the box but haven't found out how to do that bit yet. I will post again if I find the solution.

Does anyone else have a forum bug with this theme in the navigation ? When viewing a post the options at the bottom of the page to navigate back to the main menus appears whacky and I can't figure out how to fix the error. Any help in that matter would be greatly appreciated. Thanks.
