RSS feeds and Bloglines

I have had set up a blogline account and added some RSS feeds. To organize these I created 4 different folders.
The main problem I had was when I chose 6 hours for display, and thought I lost my feeds because only the 'news' feeds were displayed.
I realised then with the other RSS feeds and blogs nothing had been added during the last 6 hours, so I changed these other feeds to 24 hour display.
