It was founded early in 2005 by Jeremy. It stemmed from the original NSider forums run by the Nintendo Power Magazine, through a post in the Animal Crossing Board. The name came from a shop that Jeremy ran out of his house in Animal Crossing Gamecube. This also caused the name of the Bell Tree Fair: A massive sale. The original forums ran from nVision Free, via the off-topic board on NSider. Users used to have to be a member of NSider to join the Bell Tree.
The second Fair was around the time NSider shut down, which caused a massive influx of users to the Bell Tree. This also garnered a lot of support for the accityfolk Youtube channel, which helped to advertise.
Come 2008, the forum had moved to Zetaboards, and a few years later, they had moved to vBulletin after finding a way to transfer over all data.
The modern era started in 2011
