I just want to point out that some thing behave differently than you might be used to it:
When a name is shown in green - it indicates that the person is online. Admins or Moderators aren't highlighted in any way yet. I'll add this later.
Before you can join a ladder you have to go to the Games page and tag all games you are playing. I have added this so it is easier for you to manage bigger clans and it also avoids that people show up in roster selections that don't play this game. For the single player I have thought about showing all ladders and whenever you sign up to one you will be added to the game list, but once there are a lot of games it would become a mess so I decided to make it as it is now.
Beside that if you want to join a clan ladder you have to create a roster first.
For ranking pages: if the rank appears in green it went up, red means the clan went down and blue means it is a new entry.
Another thing that changed for admins: to make a ladder people can join you have to create a ladder, then a season and finally in the last step add ladder season settings.
