When trying to use Mozilla Thunderbird as a replacement for Spark IM because we want to remove the usage of Java in the environment, we are unable to figure how can a user send a broadcast, which is basically sending one message to many users at the same time (even if that mean to be multiple 1:1).
It should be super simple, send broadcast -> list with checkbox of users to send the message => the box for the message, then send.
That is pretty much the last thing that prevent us from moving everything to TB, please help !
