The Attack's Discord server is the main place where the community congregates. Discord is a free text- and voice-chat client for your computer or phone. Access to the #attack_free text channel is free to all. When you subscribe on Twitch or pledge $1 a month on Patreon, you gain access to a subscriber-only text chat. You also gain access to several voice chat channels that are used when the community plays online games or just for general socializing. Pledging $10 or more per month on Patreon allows access to the #vipsuggestionbox channel and others. The vast majority of the activity on the Discord is in the subscriber-only areas.

Front Page and the podcasts all extensively feature interaction with the Discord in a dedicated sub-only text channel.
