Filter for users --> copy the URL --> send the link to your colleague who has Regpack admin access.
Collaboration between admins within an organization has been made even easier. When you or another admin apply a filter from User Management or Payments, you will now see a URL that displays at the top of the page. If you want to share a specific filtered view with someone else within your organization you can send them the link while they are logged in to view that same filter!
