Hi Shanan, You can set listings to be moderated before they are published from within the Vantage admin dashboard. Users can log into their dashboard and edit as required, but moderation is not required at that point, with no specific setting to force moderation again for a previously approved listing.
The default number is 5, so it would require customization of the theme in order to change this.
If you are already using the business directory plugin (which I am personally not familiar with in terms of use), then you will be more familiar with the functionality it currently offers than I am, but at a glance the features list on their site certainly is not quite as extensive as what we offer with
Vantage. We also have a strong team of developers and support staff behind our products, with an active community as well. Thanks.
