This article deals with automatically assigned and set signatures, a feature described in detail in a dedicated article.
If you want to check whose signatures will be set during automation, the easiest way is to go to Credit Automation settings and click on "See users scheduled for set-up".
You'll be redirected to Users menu where you'll see the affected users.
If you decide to exclude a specific user from the set-up, you can do so by clicking in his details by clicking on "Cancel Credit automation set-up" at the bottom of the screen.
If you want to see which current users will be added to Subscription (activated), the process is similar, go to Subscription menu and click "See users scheduled for activation".
You'll be redirected to Users & Set-up where you'll see the affected users.
