Community Channels are identified by a tower. Any player can contribute to them. Their privileges for the channel will depend on the Community Points they have earned; the more points they have, the more they will be able to do in the channel.
Community Channels’ profiles have three tabs: Preview, Quality and Community. In the third tab, you will be able to see your role in the channel and how long it will take for you to reach the next role. Below your role, you will find a link with information about what you can do to get more points.
Bear in mind that the points are awarded only for that specific channel. This is why you may have a high score in one channel and a lower score in another.
