You have a base URL that is unique to your organization. Each event is a page under that domain. You can find the URL at the top of the "Edit Public Page" page in the "Promotion" section.
When you set up your account, you defined the base URL for your church. It is something like: mychurch.myanswers.com
If you wish to change that, it is accessible under Event Settings. Be aware any change to your church URL change will affect the URL for all events for your church.
All your church's events will have a page under that domain. We automatically create a page name based on the theme. Your URL will be something like: mychurch.myanswers.com/my-vbs-theme
You can change the page name (the part after the last slash) to something else on the Public Page Settings page.
