Communication between 2 TT groups

We have a brother troop and a sister troop that have thier own TroopTrack accounts, is there a way for email communication between them (ie custom mailing list?). The idea was for an individual in the brother troop to be able to create an email within TroopTrack and include the patrol for the sister troop and it would then be sent to all thier members.

When selecting Communicate, Send an Email you would need to use the section and put in the magic mailing list of the other Patrol.

It appears in my testing that the sending permissions still apply so this would not easily work without some major manual e-mail address authorization in the mailing lists of both units. Even then I am not totally sure it would work.

Thanks Aaron,

I tried to do that but the email was never forwarded when sent.
