UBB.threads PHP Forum Software Community Forums Resources and Customizing How Do I? Multiple Account Login?

I used to get a PM when some ne'er-do-well tried using multiple accounts to log onto the site.

The PM would say something like:

"A user from the IP 179.49.44.141 has logged in to the following accounts: TweedleDee, TweedleDumb"

Has this feature been removed?

The reason I ask it that I cannot find the option in the Admin menu and I am trying to send the PM to a different admin account!
