For those of you who receive email notifications of new content, you probably haven't received email for a few days, and then today received an email with a lot of posts which do not appear on the front page of Kairosnews. That's because the notification module was picking up the incoming RSS feed items that are stored in the new developmental news aggregator.
I've now modified it. If I've fixed it correctly, it now only sends notification of nodes which have been promoted to the front page.
Sorry for any confusion this may have caused.
