If you want to join a studio, you have to be invited to join by another scratcher. I would comment in the studio asking if you can join.
To create a studio,
go to “my stuff” and right next to “new project” there should be a button that says “new studio”. If it does, click on it and a empty studio will show up. Give it a name and some info on the side, add a picture if you want and invite people to join.
I hope this helped!
