Why don't I see my posting in Neighboring FPFs?

I opted to share my posting; why don't I see it in a Neighboring FPF?

When you post a message and opt to "share" it, FPF members in neighboring forums can click on the "News from Neighboring FPFs" link in their Forum to see it.

You won't see your own posting when you go to "News from Neighboring FPFs" – rather, you’ll see postings shared by members of the Forums adjacent to yours.
