The Cakery is a backchannel IRC chat room on Freenode. Surprisingly, we mostly talk about cake.
If you already use IRC, you can connect with your usual client.
ports (plain-text): 6665-6667 and 8000-8002
SSL ports: 6697, 7000 and 7070
If you don’t know how to IRC, the easiest way to join is the Freenode webchat app. Enter the nickname you want to use in the chat and click connect. Simples.
If you want to run a dedicated IRC client, you can find a free one for your platform from the links below, or by searching in your app store or googling “IRC client” for your platform.
