You could look through the recruitment threads posted in the
Recruitment - Social & Community Clans Forum
for a clan thats sounds like what you are looking for. (The clans in that section have no requirements for joining.)
You could post a thread in the
Recruitment – Looking for a clan Forum
to describe what type of clan you are looking for, and then clans that are actively recruiting and would like you in theirs will post an invite to you on your thread.
If you are looking for a Friends Chat, those will be under the name of the user hosting them.
Melted Butter, Timeless Horizons clan chat is open if you just want someone to chat with. But you'll also get ask to join more than once, so just tell them you visiting.
