User Tracking is used to track and restrict Number of Registered Admins and Sub-accounts.
The settings can be found under Leanswift -> User Tracking -> Settings
If the limit is exceeded, portal admin is notified with an email about it. If the count field is left empty, it is considered unlimited.
Based on the count configured, number of Registered Admins and Sub-accounts that can be created are restricted.
