OK, this seems to be the reverse problem that most people seem to be asking about the confirmation email.
Just to let people know what we're doing: We're running a Network with the Multi-Network plugin, if that makes any difference.
Anyway, when I go in as an administrator and to go Users -> Add New and put in the user information, I click the "Skip Confirmation Email" checkbox and then add the user.
However, WordPress is still sending a confirmation email out to the user. I DO NOT want it to do this. (the main reason being most people are going to be logging in using LDAP, so we don't want them to use the password they send, and there are times when I want to add users but I don't want to notify them yet)
I'm kind of at a loss as to why it's still sending the email despite me checking the checkbox
