Chat Improvement Suggestion for Correspondence

In correspondence games, anything a player types in chat hangs around for the whole game. This seems a bit awkward, especially if the comment is applicable for a particular move but it's not clear which move. Would it be very difficult to add some kind of time stamp/move number on the chats?

I second that idea.
Something simple like
15w Comment I am making while white is to make his move 15.

I third; also, might latest-first be better?

I fourth :). Same thing with draw and takeback offers, by the way.
