HI there and welcome to the 5% Challenges! If you go to this link and request a spot on a team, you'll get a response there from @Ceriusly1 who is in charge of placing members on teams.

Once you are given a team to join, you should join it as soon as possible and get to know your leaders and team mates.

I hope this helps and you have a fabulous fall challenge.

@Ceriusly1 - The post came up on my notifications so I checked it out. I know that you've been busy balancing teams, so figured I could give the basic information to get things rolling. Happy to help!
