Every community manager can select one out of 9 choices how to continue into the next season under "Administration"->"Manage Community".

At the transition into the new season only communities which have been founded before the start of the last game day of the season are respected. The transition into the new season is announced in the Comunio calendar an the community news in due time and takes about five hours. During this time transfers are performed and the transition chosen by the community manager.

Season transitions:

What will happen to my team?What will happen to my account balance?

Basic Player:

Keep team + 5 M

Every member is keeping his team. No players will be assigned.

Every member is keeping his budget and receives extra 5 M for new acquisitions.

New team, 20 M

The team will be deleted. Every member gets a new team of 15 players assigned.

The account balance will be deleted. Every member gets 20 M starting budget.

No team, 40 M

The team will be deleted. No players will be assigned.

The account balance will be deleted. Every member gets 40 M starting budget.

Keep 5, 9 M, 10 with fixed positions assigned

Every member must keep 5 of his players he had selected under "Line up". If he doesn't select them under "Line up", he automatically keeps the 5 with the most points. If he selects less than 5 players, he automatically keeps the next up to 5 with the most points.
Additionally he gets 10 players assigned: 1 goalkeeper, 3 defenders, 4 midfielders and 2 strikers. The positions of the kept players will be ignored.

If account balance is < 0, the account balance will be raised by 9 M. If account balance is > 0, the member starts with 9 M.

Keep 5, 9 M, 10 assigned with variable positions

Every member must keep 5 of his players he had selected under "Line up". If he doesn't select them under "Line up", he automatically keeps the 5 with the most points. If he selects less than 5 players, he automatically keeps the next up to 5 with the most points.
Additionally he gets 10 players assigned: The computer is trying to assign players so that you will have a team of 2 goalkeepers, 4 defenders, 6 midfielders and 3 strikers.

If account balance is < 0, the account balance will be raised by 9 M. If account balance is > 0, the member starts with 9 M.

Pro Player Communities can additionally use the following season transitions:

45 M + team + budget adjustment

The team will be deleted. Every member gets a new team of 15 players assigned.

The account balance will be deleted. Every member gets 45 M minus the value of the assigned players.

Keep 5, none assigned, 20 M

If account balance is < 0, the account balance will be raised by 20 M. If account balance is > 0, the member starts with 20 M.

Keep player up to 30 M

Every member keeps as many players as desired and selected under "Line up". No players will be assigned.

The new account balance equals 1/3 of the wealth (= team value + account balance up to 10 M).
Additionally: If the team value is above 30 M then 1,5 times the difference between team value and 30 M is deducted.
Is team value less than 30 M then the difference between team value and 30 M is added.

Reallocate wealth

Every member keeps his team. No players will be assigned.

Half of every member's wealth (= Account balance + Team Value) is pooled and then redistributed evenly amongst all community members. Half of wealth (old) + share of pool = wealth (new). Wealth (new) - Team Value = Account balance (new). A negative account balance reduces the initial wealth. It's also quite possible that debts will increase through the reallocation of wealth.
