First in the series is the Green Park 2 theme from Cordobo. This theme uses a little jQuery to manipulate the DOM. This is due to the next/previous control showing an error message as this control is situated in the sidebar. Also the RSS link is copied so that the subscribe section replicates the syndication link on the top. Should it not find the link the section is not displayed.
Very nice theme, easy to look at and very easy to navigate.
