Hey there.
It is possible to hide s2member Level Restriction Panel (see image)

And show it just for administrators ?
Is that showing to members when posting in bbPress? Or are you talking about other users you have another WP role to in order to create/edit posts?
Regarding protecting individual topics, if you have the topics include something in their permalink that will let you spot all topic URLs, then you can try using the URI restriction for that. [hilite path]Dashboard -› s2Member® -› Restriction Options -› URI Access Restrictions[/hilite]
[hilite path]Dashboard -› s2Member® -› Other Integrations -› bbPress®[/hilite]
* Note, it is currently NOT possible to protect a Forum, and have all Topics inside that Forum protected automatically. In order to accomplish that, you’ll need to use s2Member’s URI Access Restrictions. We’re working to improve this functionality in the mean time. Also, s2Member is currently NOT capable of protecting Topic Tags; but you can use URI Restrictions for these in the mean time.
I hope that helps. :)
