How enable Skip Confirmation Email checkbox for individual site admins

Because SuperAdmins are (supposedly) more responsible. It’s was originally a security thing.

https://core.trac.www.ads-software.com/ticket/22277

Some background: This was deliberately for multi-user setups, to prevent random administrators from spamming other users with invites. (Until maybe a year or two ago, WP.com still allowed only emails.) Obviously, it does not make sense for more traditional networks. Making that a distinction across core could go along way to solving not just this.

However we do have a plan to change that ?? Just hasn’t been done yet.

Thanks Mike for your reply.
It seem to be come at 3.8.
Until that time, how can I trick to solve it?
Is it possible to make trick by adding filter or something to theme’s function.php file?
In my project, online user adding is closed. Only admin can add user to discuss the common project at project management page. So, security risk is under control.
To solve this issue is very important to track project schedule.
Thanks at advance for your cooperation.

You could upgrade to the nightly release of WP? 3.8 is due out mid December.

It is risky to do now. I can’t know the behaviour of tens plugins at that point.
Thanks
