Camo that’s not a solution [at least for me], in UAM you can make the same, here are my results with your option:
If I select “No-Non-members…”

Then The first message is shown, but I can also see the other (hidden) posts [look at left column] [although i can’t see the info in them, because it’s hidden, I see them, so they are not secret]

If I select “Yes – Only members…”

Then the first message is hidden, but also the posts [what I’m looking for]

So, this is not a solution if you [as me] want to show the first message, but hide the rest of posts.
Hi! I found the problem, but not the solution,
I realized that if I check the option in the UAM to “Hide Potst” completely it also hides the first topic; if i unchecked it, the first topic is shown again.
Maybe it could help for anyone who understand the mechanisms of those plug-ins.
-Sorry for my english, i’m spanish and i’m using the spanish translation, so i can’t say exactly the option to check or uncheck, but it’s the first one in the Adjusts/Options for UAM-
