ICR stands for "Items Creation Reminder" and it's a kindly way to tell member to remember publishing their products or services (Create Items) because you might be interested in any of them, either if the member has not published any product or service yet or if you wish to see more of them.

The member who receives the ICR is notified via email and with an in site notification, along with a banner at the top of the Home page, from where is able to reply or delete it. Replying this reminder means notifying the member who sent it that the product or service has been published, while deleting it means just dismiss it.

Sending an ICR works in a similar way to Poke a user in Facebook.
