Well, I DID join a tribe that I've forgotten the name of for a day in my very first days of playing Transformice, but I soon had gathered the 500 cheese needed to create my own tribe. I spent the next 5 months in that tribe, called Illuminated Cosmos. I'm no longer in Illuminated Cosmos even though it does still exist, in new ownership.

Saints Sex Slaves I believe.

Lama something

NeonX. I left because the leader, Cutefroggie was very inactive.

deleted.

idk

My second tribe : Elementaire

Fresh Irony, I believe the tribe went inactive or was destroyed.

I have no idea, but it was weird. Then i joined an ex-friends tribe, but because she was so mean we had to leave that tribe and me wanting to be in a tribe again said with my 2 other friends (who are now alpha-betas in the tribe) cheesefarmed and then I created my own tribe and my first rule was that only close friends to everyone in the tribe could join, then nobody would be uncomfortable.

can't remember

An Indonesian tribe, something like that. I don't remember.

I believe that is "Reggae xD" or something similar

I think it was The Portal That Leads to Nowhere.

I Joined United Mice Kingdom-- my irl friend showed me Transformice and I joined her tribe and I love it :3

The first tribe i joined was a tribe made by someone my friend was close to! Eventually this person became my friend too. It was called Freaking Fantastics, it was fun ^^
