Hi Allen - I have been searching for days (weeks) for something like this and was very eager to try it so I downloaded and installed and added feeds. When I get to the shortcode tab, there is this error.
Cannot open the file /home/myusername/laughltemplatesasinodirectory.mysitename.com/wp-content/plugins/wp-rss-multi-importer/templates/
here's the thing my site name is laughlincasinodirectory.mysitename so I do not know where that first name is coming from.
I wanted to be able to use one of the special formats.
I also could not open your template link to see what they look like.
