Thank you for your requests, @Aztek! I’ve added them to the list for you. 
Unfortunately, there’s no method at the moment to be notified of when a request has been digitized and added to the platform. We are also unable to share wait-times.
I recommend you regularly check back at our “What’s New” and “Coming Soon” threads in #watchtower to see if a specific request is going to be added. Some users keep a running list in this thread of recently digitized comics as well.
