unfortunately I'm not strong in this topic, so I have a question, why on your site I did not see the team? So it should be? this is normal?
The website mentioned in the OP is no longer up to date and will be replaced by a new one soon (tied in with the network launch) Karma made an extensive update a bit over a month ago which is more or less accurate in terms of who is doing what:
