Share is located under the Navigation tab, and Boundaries grouping
When you share your boundaries and contact information, you allow all MT4 users to automatically send you addresses in your language and that are within your congregation boundaries.
Instead of having to contact all the congregations to give them your information, or to rely on the congregations to contact you to find out your information, by clicking the Share button, the information will be automatically sent to all current and future MT4 users.
You can also send your boundaries to congregations using other applications. After the boundaries are sent to the Multi-Terr team. you will be prompt if you wish to share your boundaries with other recipients.
