Can captains bring their permanent team to my pickup game?
Yes, by default: a new game starts with both “Solo” and “Team” on in the “Join Type” row (“Solo and team”). Turn “Team” off if you want players to join only one by one (solo only, no teams; «только по одному», «без команд»). The game stays a pickup, and a captain or owner of a permanent team can then bring teammates through checkout (in the team option “Add friends or a team”, tab “My team”). The setting is off by default, can be turned on or off later when you edit the game, and does not exist for leagues. If you turn “Team” off, the message “Teams that already joined stay in the game.” applies: only new teams are stopped.
Each team plays as its own side when you confirm lineups, topped up with solo players if needed. If lineups are already confirmed, new teams cannot join and a captain cannot add players until you reset the lineups; once the match schedule is generated, teams cannot change at all until you reset it.
The captain pays for the whole team and fines for teammates go to him. If a team is deleted or a teammate removed by you from the team page, every spot is refunded in full, with no cancellation fee, to whoever paid for it. If the captain deletes the team himself, the normal cancellation policy applies to the payer.
