Nintendo Dojo, abbreviated as NDJ, is an online community that was started by certain Smash World Forums members. Initially started as a Super Smash Bros. Brawl-centric site under the name All is Brawl, the site was renovated in response to Super Smash Bros. 4. The site started the "All is" network, designed and run by Nealdt.
Nintendo Dojo's primary purpose is to bring the online community of Smash Bros. together and it allows for users to create various user groups (be it for crews or for socializing) and host their own tournament via a program known as tio tournament organizer. This feature is used for hosting tournaments for all three Smash games, as well as both online and in-person Brawl tournaments. The site is also home to its own ladder rankings system, where any user is welcome to join and challenge others to increase their rank. The ladder is updated on a weekly basis, and makes use of the TrueSkill system, the same program used by Microsoft in its online ranking system. Another feature of Nintendo Dojo is its chatroom, with 8 different categories of subjects discussed. This includes a tourney chatroom, with four different rooms to allow tournament organizers and participants to communicate without interfering with other chatrooms or receiving such interference. Users can also upload videos via YouTube, such as technique/combo videos and recorded tournament matches.
The Nintendo Dojo community is active and large. Users have the ability to design their profile, leave each other shoutouts, blog, and use the site's forums and chatrooms for social and recreational purposes (in addition to their usage to discuss Smash).
Nintendo Dojo is also famous for its very organized Brawl Stadium community. Smashers from all over the world come to post their records for 1-P modes such as Target Smash, Home Run Contest, and Multi-Man Brawl. Smashers like Sin2324 are active on the boards, along with OWLET, LinksDarkArrows, Nismoe Joe, marth1 and super-mod Nessy.
As the "All is" network aged, Nealdt slowly became increasingly more difficult to contact. All is Brawl downtimes became long and frequent, spanning weeks with no warning or explanation. Ladders became impossible to run correctly due to requiring Nealdt's presence to reset them. Server issues resulted in the mass deletion of old user blogs and messages, instead of simply buying more server space. The DDoS attack of late August 2013 brought down the site and damaged several parts of it. Finally, in November 2013, the entire "All is" network went down to a "service unavailable" page. The site reappeared on December 11th, 2013, explaining the downtime as massive database corruption resulting in a full-on server upgrade.
With the approaching of Super Smash Bros. 4 and the shutdown of the Nintendo Wi-Fi Connection (making it impossible without hacks to play Brawl online, the site's main purpose), it was expected by most users that significant change would be coming. It was known (via mostly technical reasons more than official announcements) that the site would be renamed "Nintendo Dojo" at some point in the near future as part of this. The site was officially renamed and moved to nintendodojo.com in October 2014; all previous content was carried over.
