Minecrafters was a group that dedicated their entirety to the Minecraft section of the forum, as well as running an official Hack Forums Minecraft server. The group wanted to improve the playing experience for all Hack Forums’ Minecraft players.
While Castle Bravo owned the group, he was being assisted by his chosen leaders Pink Flloyd and Barneyyz™.
The idea was originally provided by Pink Flloyd, as you can see here which received an overwhelmingly positive response. Needless to say, the community was excited for the new official Minecraft group, as during this time Minecraft was nearly at its peak population.
