It's a very nice feature in my opinion. Wont take long 2 add it in to XenForo + alot of ppl will apreciate it. One of the pluses - when your forums r overrun by spammers, you can manualy control it if you want. No need 2 install any addon etc.
Should be placed within the Admin Control Panel in ?users/list
Thank you! Hope you will understand the importance of this feature.
In AdminCP > Users > Search for users you have a menu in the top right with "Common searches". There you can select "Newest registrations" that will display all recent registrations, including non validated users.
