You choose when you participate according to your schedule and interest.
All of the astrological charts will be combined to form a group chart. Based on the group chart, Stephanie will find dates that are best for visualization for various needs, i.e., prosperity, healing, relationship, employment, fertility, safe travel, etc.
If the visualization is one that you want, then call Sheri to be added to the recipient list. Once enough members have committed to participating as the visualizers, Sheri will confirm everyone and provide the actual visualization to focus upon and the exact start and end times for your location.
Everyone seems to have their own preferred methods and you are welcome to share your visions and messages.
