WPMU remove wpmu_welcome_user_notification

Super Admin -> Options, there’s a section there to uncheck the ticky box that says:

“Registration notification Send the network admin an email notification every time someone registers a site or user account.”

Thanks Andrea. I found that chackbox. But I’d also like to stop the mails sent to the user.

We have our own system to do that. So I don’t want our customers to get 2 mails for the same thing.

it seems that I found a solution:

i wrote a plugin whick hooks the the 2 functions ‘wpmu_welcome_notification’ and ‘wpmu_welcome_user_notification’

I simply killed the wp_mail calls in them and replaced them with a none-sense function.

Here is my code:
`
function my_nonesense() {
return true;
}

remove_filter(‘wpmu_welcome_notification’, ‘wp_mail’);
add_filter(‘wpmu_welcome_notification’, ‘my_nonesense’);
remove_filter(‘wpmu_welcome_user_notification’, ‘wp_mail’);
add_filter(‘wpmu_welcome_user_notification’, ‘my_nonesense’);

Just what I need, but the above code isn’t working. I placed it inside an existing plugin. Any ideas?
