I was wondering how this plugin compares with  the two below for wordpress.  I am looking for something that allows  one to cross cross post items to facebook groups  either from the oxwall newsfeed or from the wall in a group. I am especially interested in syncing up the comments on posts on both oxwall and a facebook group.  Here is a plugiun that does that for wordpress
