Wow, awesome, thanks for the quick reply!
No, not with this recipe. You need to go to the Calibre Recipes sub-thread and ask about creating a separate recipe for that specific site and not use Google Reader recipe for that site.
The thing about this is the following:
My favourite newspaper doesn't supply one overall RSS feed but several ones. What makes it even worse is that there are usually only 15 or so entries in each feed. This is the basic reason why I started using google reader this morning: I want it to collect the news out of several feeds over 24 hours and let calibre create my personalized paper in the morning.
Are you saying this is not possible? I have been searching for a solution all day and this was my biggest hope so far...
Edit: maybe by integrating the Cailbre Recipe into the google reader part!?
