If somebody in a team drops out of a Delta, the remaining players have a choice. They can either choose to continue with an ‘empty seat’, or they can choose to begin again with a new player.
If a whole Delta collapses, it may reform with a new set of players, and you can start over without any additional cost. Once you have purchased the Delta Programme, you will have ongoing access to the resources.
This scenario is one of the reasons it’s so very important that you consider carefully if you’re ready to make a full commitment before joining the Delta, as it obviously has an impact on and inconveniences not only the person who drops out, but the whole team.
