What he means is that when you send a unique character to the chatroom only mIRC users will be able to see it. Users of other programmes will not. We all know mIRC dominates by far over anything else and all else added together but that is not to say that mIRC should 'go it alone'. There has to be some sort of conformity or at least discussion with the authors of other programmes and indeed IRCd's when wanting to commit to a feature or function that would otherwise stand alone.
