Stop email notification for Group Access changes?

Hi,

How can I stop the automatic email that is sent out every time I change what Group a member is part of?

I don't want them being notified what group I'm putting them in. Plus when it sends the email, it sends them a direct link to a list of everyone else in that group, which is not good. Even though I have turned off the group memberlists in the forum, the direct link in the email bypasses that and lets people see who's in the same group.

There isn't anything that we can do to remove it. Click the status of the group as hidden.
