tab only for owner's profile and administrator

I want the connections tab to appear only to owner's profile and to administrator, how can I do that? Also, is there a way, in the connections tab, to show a determined field besides username and the email icon?

Thank you,

Jesus

You can use CB Privacy to let the user control who can see it. You can also use CBSubs Fields Tabs Protection and protect it with a plan that no one will ever be able to obtain then set the protection to be ignored for owner and moderators.

Also, is there a way, in the connections tab, to show a determined field besides username and the email icon?

Unfortunately, no, not without editing the Connections plugin.
