It's not too late, Ann!
The Alt-kerth channels aren't password protected, and the ceremony isn't for another (almost) 2 hours!
Step 1: Download an IRC program. (For Windows, use
MIRC )
Step 2: Connect to any Undernet server (It'll have "undernet" in the name)
Step 3: Join the AK channels.
/join #altkerths
/join #altkerthchat
Step 4: Enjoy!
For more info, you can check out
this thread or just ask!
