Hi all.

I have a site where I would like to add the following capability: a special section of the site (likely an organic group) will be locked from your basic authenticated and anonymous users. The section will have a forum and other basic types of content.

I would like to assign one moderator to that section of the site that is able to control who is granted access. So one person would be a "moderator" and people can join the group by invite only. The people that join would be authenticated users ideally.

It is important that no other site users (asides from admins of course) be allowed to even know of the groups existence, let alone access it. Thus, if I create public groups later on and there is a list, I don't want this particular group to show up anywhere else and anyone attempting to access the group gets access denied.

It would also be ideal that the group pages not be sniffed out by a robot as there will be copyrighted material and so I don't even want Google to know about these pages.

I am relatively certain I need to load Organic Groups and OG Forum, but what modules are needed to meet the rest of the requirements and how do you keep a specific section of your site from being autonomously added by Google and related engines? (I still would like the rest of the site content to be added.)

Thanks in advanced fellow Drupalers.
