FiMchan wass a My Little Pony: Friendship is Magic imageboard, usually depicted as Ponychan's main rival, established by /co/lts. It was not nearly as popular as Ponychan; however, while Ponychan is strictly PG-13, FiMchan adopted a more 'Post whatever you TOOTing well feel like' attitude.
FIMchan was commonly accepted to be a "dead board." It ran an outdated version of Kusaba X that hadn't been updated in a long time, and required CAPTCHA to post in later years. Much of their traffic has been taken up by MLPG.co , and a little from MLPchan.
FiMchan was taken down sometime in January 2014.
