At the bottom of the session formation page, there is a list of players that reflects the current settings of their company (area, number of fields, and region), as well as their readiness to start simulation.

You can expand and collapse the list by clicking on the icon in the upper-right corner of the list.

You can go to the user's public statistics by clicking on the “View profile” button, which appears when you hover the cursor over the user's term in the list.

The session Creator has the ability to remove players from the session.
