I am unable to successfully import any RSS feeds that I have tried so far.
One feed refuseses entirely to import anything showing "Campaign processed. 0 posts fetched"
The second feed, managed by FeedBurner worked but it imported a geometric square of the posts. ie. there were 7 posts but WP-o-matic imported 49 posts, 1 original and 6 duplicates of each. I then deleted all the posts, and reset the campaign selected fetch and again got "Campaign processed. 0 posts fetched" for this second feed too.
