Errors on Waitlist...

In regards to our Wait List, during testing we noticed the following errors:

1) Our customers are not receiving the email notification when they sign up for a wait list.
2) When a product quantity is updated, the customers that signed up for the wait list are not getting the automatic notification.
3) Where can we manage the subscribers for the wait list, so that when a customer who is not signed in signs up we can see their email and communicate with them if need be.

That is a lot of information to review. Is there a simpler answer to my questions?

1) How can our customers receive the email notification when they sign up for a waitlist?
2) When a product quantity is updated, how can customers who signed up for that waitlist get the automatic notification?
3) Where can we manage the subscribers for the wait list, so that when a customer who is not signed in signs up we can see their email and communicate with them if need be?

Thank you for this information. Was really helpful! For #2 When I click on "Create/Edit your Cros task" to make sure my Cros is activated properly its prompting me to renew my subscription. Must I have a registration to access such just to view it?

It appears correct on the surface though, see attachment.

Thank you! It works now!!!!!

Customers are now able to get notification once a product has been updated.
