A Prayer/Comment wall is a great way for your users to make comments about your organization or things you have going on. There is no approval process for the these comments. Therefore, they can be good or bad so make sure you monitor what your app users are saying!
You can have people comment on an event or service, or just have a simple prayer wall.
This page can be moderated at any time if someone posts information that you would like to delete. This moderation happens on your main dashboard page.
