I have some requirements for a Community program, and I wonder if all these are possible with BuddyPress.

(1). We want to be able to create a large number of groups, we are only going to allow appx 20 people in each group. So at that point registration for that group needs to clstose.
(2) These groups will be private for those 20 members. They are not open for others to join nor can other groups see what is discussed in that group. Prefer that the other groups don’t show if possible, at minimum – a note that they can’t access that group.
(3) From admin – we want admin to be able to post a message in bulk to all groups or to selected groups in admin
(4) User needs to be able to shut off or turn on email notification.
(5) We don’t want the number of people to show for their group during registration for it.
(6) We do not want them to see admin in the groups. They want to respond and ask questions to admin, when we want them to use our ticketing system.
(7) During registration we want to offer a the groups in a dropdown – but once it hits the maximum number, it will show as closed and they can’t select it to be a user in it.

Are these items possible with BuddyPress and Premium Plugins? If so, any help on those plugins I need to be looking at would be fabulous.

Thanks
Tina
