TeamWars Help

Hello,
I need some help with TeamWars section of the dashboard.
Having a few issues.

1. I created a team, but no one can join it. Only challenge it. I have looked all around, but i don’t see where other users can join teams that I create.

2. Matches..
1. Can’t create “maps” for matches.
2. Can’t see Matches on webpage. There is no page with matches on it, for users to see on the website.
