pin a comment in a chat or channel
Allow owners to pin a comment in a chat or channel so you can either direct people to another chat or channel. or lock a message. The pin locks the message at a point that is visible to all and doesn't move from the pin space when people scroll through the chat. Example: pin a notice that they are in an old chat and a new chat is on another <channel> or <chat> and this channel will not be monitored on a regular basis. And after a time the chat will be unavailable.
