We have established a mailing group to support this event, which can be found at: groups.io/g/obsidian-wave. If you would like to participate, we encourage you to join the mailing group and participate in training, which will be announced to the mailing group. Taking part in the training is encouraged because the event is relatively complex. We look forward to your participation in this exercise, as well as follow-on exercises.
