UBB.threads PHP Forum Software Community Forums UBB.threads Version 7/8 Support Where is the 'admin email to notify' of new users setup?

I apologize, but I just can't find it.
Looked everywhere.

Where does one set, the email(s) that should be notified when a new user joins?
When I did the threads install, it picked up and imported my old setting from UBB/Classic, but now I need to make a change... and can't for the life of me find it anywhere.

Thanks!
Andrew
