I am using 7.2.2

I have a Post Island set up for Recent Posts. I selected the forums I want as Source Forums - which is all but one forum that is for Admins only.

The problem is... when I make a post in the Admin Only forum it is showing up in Recent Posts, even though I do not have it checked as a Source Forum.

Is there something else I need to do?

Make sure you did not select the category the admin forum is in.

Checked that... I do not have any Categories checked - just forums.

What about at the top of the list "All forums" is that selected?
You also might need to clear cache in the control panel to rebuild the island.

Thanks Ruben! That was it - "All Forums" was selected... didn't even notice that.

Thanks again!
