This issue is about the links under 'References' on the front page, they are no longer online. I have found some replacement links that look to be the same content. Cheers!

'Omega part 2 intro: Using Delta module for contextual layouts'
Replace with:
http://developmentgeeks.com/blog/using-delta-contextual-layouts

'Presentation on 960gs and the Omega theme from DrupalCamp Montreal '
Replace with;
http://dev.developmentgeeks.com/drupalcamp-montreal-advanced-960gs-themi... - or -

'A blog post that outlines the concept and initial work on this module'
