I know I saw this somewhere but can't find it.
Any help appreciated. I am running latest version.
Log into your MyBB admin panel, and click 'Change' under 'Board Settings.' Then look for: 'User Registration and Profile Options.'
On this page, you'll find 'Maximum Registrations Per IP Address.' That's what you're looking for.
I noticed that it allows 2 within a certain time frame. After that time frame they can register again. I can set that to many hours BUT that rules out multiple people in the same house. Any solutions.
