Bump,
I sent an official warning today, but included the other mods on the message, which removes the warning.
Would it be possible to keep the warning status if the other invitees are mods? What I wanted to do was roughly equivalent to cc: the other mods so they know what is going on. Sending a warning, then sending a second PM to the other mods, then repeating that for any subsequent conversations seems a lot of overhead for a fairly straightforward communication.
