Site featurestournaments 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 AiB 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 AiB 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).
While AiB is primarily focused on Brawl, all of the features used for online play can be used for the remake of the original game for players that are using Mupen64k to play online.
AiB 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. Even world famous smasher Sin2324 is active on the boards along with OWLET, LinksDarkArrows, Nismoe Joe, marth1 and super-mod Nessy.
