Here you can find a update list of teams and their members
If you or your team mates name is coming up as red you did not pass the Honour level 2 check and cannot play until your account reaches Honour level 2.
If your name is coming up orange you did not provide the correct summoner name (remember your summoner name is what comes up in game and now what you use to log in with)
If your name is green, there was a mistake or typo in your summoner name but it has been fixed.
You can browse through the tabs to see all the different tournaments and teams.
