How do I change my church's name or address?

The name: go to Admin → Settings → General, Profile tab, change Church name and click Save. You need the Church settings: Manage permission, which the Owner and the Administrator have. On the same page you can change the timezone and the currency. Check the Language field before you save, because saving stores it as your church's language too.

The address (slug): you choose it when you create the church, and there's no setting to change it later. It's the short name used in the address of your public church pages, e.g. /k/bethany-church. If you need a different one, write to contact@worshippro.net from the owner's address.
