Make my Nabble forum more private (for now)?

[Swambast]

Is there a way for me to make my Nabble Forum more private/restricted?  I read with great interest something that Graham Perrin was posting about here:  http://freeman-centre.1486342.n2.nabble.com/user/Unauthorized.jtp?node=1489538

It is a feature that I am also interested in using, and wasn't sure I could do this at the current time, or this is planned for a future enhancement?  If there is that capability, some guidance would be appreciated...Thanks kindly for your reply!

The configuration you are looking for is probably in the forum menu "Options > Users > Who can view & post?"
Here you can find some explanation: http://n2.nabble.com/help/Answer.jtp?id=20

Is this what you need?
