It is common for league play to be extended with more divisions and/or more teams per division.
Follow the basic rules below.
1. Enter the new game times and extra times under Settings/Schedules. Be careful
2. Go to New Round and follow steps 1, 2 and 3 as usual (as if no change was made - do not add any new teams yet)
3. Go to New round / Groups. Change the game template for the groups that change the number of teams. The new template should reflect the new number of teams per division.
4. Add any new groups, i.e. divisions
5. Go to New Round / Players. Move and add new teams
6. Continue from point 4 in the chapter New round
