There seems to be no option to add other dnn roles to group default roles, just the two group roles (admin and members). This forces me to walk to each new group and add unauthenticated users if i want to reveal the group forums to the world. Would this be hard to augment to allow other roles to be added to our default settings? thanks, drew..

I agree. It would make sense to allow "public" groups use a security config for forums or even have control over forums they want to make public and those they don't....like a mini cp for group admins.
