well, you may have to create a new template to make this happen if the theme doesn’t already have one. however, bear in mind that Obscura says it’s a child theme of Thematic and on the wordpress theme repository it says that Thematic hasn’t been updated in over 2 years which means it “MAY’ work on the latest version of wordpress (or at the very least look right but actually be a wide open door for hacker types…) but it’s quite likely to run into trouble with plugins and the latest version of wordpress.
i’d highly recommend finding something else that’s better supported and current with the latest version of wordpress!
