Good morning Joseph, from your AOTK page, on the right side is the 'Chat' button which brings you to
https://animeotk.com/forum/javachat.php - from there, typing in '/join #fantasyooc' will bring you to the community room for the caravan. Unfortunately, we've lost a lot of activity in there. You might have better luck just making sure you are in the #animeotk channel (which you will enter by default in the Chat) and saying hi to everyone there.
Sorry I forgot to respond to you! Let me know if you have any other questions!
