FeedWordPress pingback

Hi,

For few days i am trying to find some solutions for my site for “pingback”.

The site is a RSS News feeder and i am using FeedWordPress for RSS feeds.
I did chose FeedWordPress cause is works quite good, and dose not consume high CUP resources, like Wp-o-Matic (this gave me a lot of hight work.).

So.. the point is that FeedWordPress is not making ping back.
I am looking for a solution to pingback the source of the RSS NewsFeed.
Till now i did failed, with our bets friend “google”, so i decided to ask some help here, if.. anyone has a solution.

Thank you.
