Make it impossible for a customer to log in until the account has been activated by the admin.
This small extension makes it impossible for a customer to log in to magento, until the account has been activated in the adminhtml interface.
Customers - Manage Customers - (select customer) - Account Information - Is activated
You can also select email notifications for the admin (when a new customer registers) and for the customer (when her account has been activated).
New customers can be configured to be activated by default. This can also be done on a per group basis.
The Extension was designed to be used together with the Netzarbeiter_LoginCatalog extension. Netzarbeiter_LoginCatalog only shows products to customers that are logged in. There also is the Extension Netzarbeiter_GroupsCatalog2 which may suit your needs better, you have to evaluate yourself what is the best solution for your case.
If you have existing customers prior to installing the extension, they will be deactivated by default. You can easily and quickly activate all existing accounts using the mass action found above the customer backend grid.
DELETE FROM eav_attribute WHERE attribute_code = 'customer_activated';
DELETE FROM core_resource WHERE code = 'customeractivation_setup';
