Caboose was a moderator on MCCP.
In the shift to the new forums, RFS promoted various members to moderators, and Caboose, while new, was chosen. His position as moderator did not last long; Caboose had a humourous approach to all apects of the forum, making many friends (such as Vital Viper), and his promotion was controversial. After being attacked several times, Caboose seemed to take a more serious approach, before slowly becoming more and more inactive. This inactivity was a result of 'family issues', however Caboose never explained much about this. He has since left the forums, remaining inactive since.
He was well known for his humour, and his relatively famous signature using the Club Penguin font he claimed to have created himself. His signature is still on his profile.
