Look in your profile. At the bottom you should see two TEAM badges. Both will be faint because you have not been assigned a team yet.
If you go to the below thread, look at the 'rules' at the top.. Complete one of the tasks and mention it in that thread.. Then Lara will assign you to a team when she works your post.

Regarding the two TEAM badges, when you have earned a badge, it will be a more vivid color. What shows up when you click on the badge gives you a brief description of what the badge is, but it does not mean you have earned the badge yet until the color becomes more vivid. as indicated below
