hi Nic, attached is the free version. I noticed that there are many 'authors' available in the feeds. customise the recipe to include any other feed you want.
RE paid content, have a look at the wiki guide:
http://bugs.calibre-ebook.com/wiki/recipeGuide_advanced
you need to customise the fields, but the recipe will then be able to fetch the content as it is. (it looks like the feeds contain already paid content, but calibre fails to fetch these articles because they require subscription).
