Yes, you can create multiple KidEvent Pro users and admins.
To do this, navigate to the setup drop down menu, select Admin, then User Management. It will allow you to enter the email of the person that you want to add. An email will be sent and that person has to click a link in the email to set up their account.
Once it is set up, someone that already has admin rights (such as yourself) can log in and make the new user an admin, too, or you can leave it without admin rights.
