Hello, everyone: I've got some questions about XFs private messaging system. I rather expected an e-mail type interface with the usual options of multiple recipients, CC, forward and BCC. But what I see here is just one option, and that's the ability to add a recipient to the conversation. Unless I am missing something, there's no option to remove that user, once added. Suppose you add someone in error to a sensitive conversation? I also don't see ways to forward a conversation. In addition, sometimes I might need to BCC a moderator with a disciplinary-type message to a user and see no way to do that conveniently. Please forgive me if it's right in front of me and I am being a doofus, can someone help me to understand better? What's the logic behind the design? And if these features are indeed missing, is there some path forward to make them available?
