We've purchased EasyDiscuss (see hidden info) and are trying to configure the system so that only ONE User Group has access to post responses. --- That's the easy part.

However... we have an additional requirement:

That Members of the User Group can only post responses in Discussions to which they have been invited, by either:

a) other members of the discussion, OR
b) by the moderator. (admin)

Can EasyDiscuss can meet this requirement?

If yes, fantastic! How to ... ?

If not, what would be your suggested approach to implementing this within Easy Discuss. (custom code / hiring you / etc.)

If you don't think EasyDiscuss is a good fit for this use case, can recommend a solution which might be able to accommodate this scenario?

Thank you so much in advance for your help, and keep up the AMAZING work you all do!!!!
