Hi @Adelaidehouse,
Many thanks for your post.
Within the R4 chat you can only talk 1 on 1, however you can from the chat window send a message that allows multiple people involved.
R4 Main Menu > Chat > Send a Message > To > Include people required
It is more of an eMail style format but that will send the message to both, it should still pop up at the bottom advising you have a message.
Regards
Matt
