From our groups, We should be able to send a message to everyone in our group under the Request filter. We could use a button similar to "Invite Members". if we had that, we could do lots of stuff. For example, if we were in a lottery group, we could send a message that a new lottery is open. Or if we were in a magazine/newspaper group, we could send out a message when the next issue comes out. Or millions of other uses.
