The ‘Discussions’ icon can be found both in the top right corner, as well as on the Athlete’s dashboard:
The goal of this ‘Discussions’ functionality is that two or more users can discuss topics about a certain athlete, whereby this information is then stored on this athlete’s page.
Only the users who are invited in the discussion will see the content of it.
It is thus possible to discuss topics about an athlete, without the athlete knowing about it, since he was not invited to the discussion.
General info: user functionalities depend on the roles & permissions settings. If a certain functionality does not work within your user account, this will be because you don't have sufficient permissions for this.
