You have to have an account to use the ADR finder. There are paid accounts that give you full access to everything TP offers, and there are free accounts that allow you to use the ADR finder.
I found it a real challenge to figure out how to sign up for the free account and then using it became an exercise in frustration. Every time I got an alert, the ADR was gone before I could sign into
MDE. I wound up getting the ADRs I wanted on my own by checking randomly and more frequently as the dates drew closer.
