How do I ensure I'm giving the right user moderator access?

[vanessalaw]

Hi there,

I've got a few users in my system whose name is Christina, I would like to give 'christina74' moderator access, but when I search for christina74 I get no results. When I search for christina I get a lot of results, but no way to distinguish between users.

Is there a way to tie a user back to their buddypress ID from the admin panel?
