With WP Greet Box 6.2.3 activated, Woo - Feedback (part of the theme, Kaboodle 1.0.2 by WooThemes) gets a separate instance of <div id="greet_block"> inserted at the beginning of each quote.
That means the HTML doesn't validate (with all those id's matching) and there is a display issue in Firefox (tested versions 4 and 5) on my Mac (OS X 10.6.8) where the first line doesn't indent.
The first line indents just fine with WP Greet Box deactivated.

7 errors, all are: ID "greet_block" already defined
