Very often (at our club anyway) people arrive after the groups have been set up. In that case, use the “Check In Player Arriving While Groups are Playing” button to add someone to a group, without the need to start everything over from scratch. Similarly, if someone leaves and you want to just remove them from a group, use “Remove Player Leaving Early”. If you want to move someone from one group to another, use the “Move Player to Different Group” button. And if you want to rearrange players within the same group, you can swap player positions by using the little arrows on the far left of the group page.
