"be the first of your friends to recommend this"
Note: I am not logged-in into my Forum nor am I logged-in into FB.
then when I go to "Members > Recent Activities" I can see (in the sidebar at "FB Recommendations") that this very thread in fact has been recommended to Facebook by a member or person.
Something is wrong here!
Please let me know if you need the URL for my Forum for you to check this out.
