Will I be notified of new orders?

Yes, once you turn alerts on. Every order appears under Orders → Manage Orders. When the admin asks Turn on notifications?, click Enable to get a "New order" alert on that device. WCart does not email you on its own — to get an email for each order, put your address in Bcc on Settings → Web Settings → Email Provider and you will receive a copy of every order confirmation sent to customers. Test orders don't trigger either alert.
