WordPress MU

I am looking for a plugin (or a hack or a built in function) that will hide user email addresses from non-admin under the Comment Management section. I believe I'd seen one before (for WP) but I can't locate it again and I'm not sure if it'd work for a MU set up.

Basically, a few of our users have expressed discomfort with their personal email addresses 1)being sent in comment notification to posters (this I think I can edit out of pluggable.php) and 2)their personal e-mail addresses being visible under comment management, especially in multi-author blogs.

Would there be a way to set this so that site-admin could still see the e-mail addresses, but users couldn't? I would be fine with removing e-mail addresses from the comment management entirely, but that could present a hassle in the future from a moderation standpoint.

Thank you :)

I believe this is the thread you were thinking of:

I gotta admit that I would just remove the code in question and keep notes on what specificially removed. Either that or find where the ip address is being put into the database and replace it with a dummy number.

Thank you for that link! That helps with part of the problem.

Actually, our users are less concerned with the IP addresses than they are with the email addresses. They don't mind people knowing their IP, they just don't want to be contacted privately through their personal email.
