- KiraPira (Joined mid- YTR)
- During the chat`s active days, you could potentially be put in a YouTube video if you are in an argument with another member. Most of these were recorded by Raykidd227 and/or SMUSX. These said videos are nearly non existent now
- Most people who had a certain distaste for the replacement chat YouTubeRangers were from DoubleMRoom before. Mainly because of the past actions of the new owner (Starman3) . Fortunately for them the YoutubeRangers chat room is no longer active as of 2013
- Double M Room could also be called: Double Mario Room, 2MarioRoom, Mario Mario Room, 2 M Room or M M Room. It is an obvious reference to the main owner MarioMario54321
