can you broadcast a message?
or whatever it's called

I remember you could send TC to someone
and they'd send a message displayed over the screen
of all the in-game sessions of whatever you said

That still a thing? how does one do this?
thing phish linked, but its very important to mention that tori broadcast is strictly to be used for globalling servers (as in, advertising your betting server) and should not be used for any other purpose (such as sending messages to everyone using them)

abuse of in-game broadcast usually leads to a warning and, in worst-case scenario, a ban
