If there is a large workspace with dozens/hundreds of team members, it would be useful to prevent someone from doing something like "Email Team.." without realizing how many people they were about to spam with something.

I'm thinking a role to make it user specific as to who can and can't do that.

The alternative might be to "enable a moderator" or something so that someone filters the messages before they go to all. Perhaps this could be a workspace attribute of some sort - whether or not people can freely contact everyone.

I'm suggesting this because it is something that happened to me - because someone had a question. Perhaps another alternative, or interim solution, is an element or option to contact the Workspace owner or designate team of "administrators" who can help.
