$WAGLOBAL_Verification_Email_BCC

Can I put more than one email address in BCC? and would I just use a comma for seperating?
Like this:

$WAGLOBAL_Verification_Email_BCC = "name@email.com", "name2@email.com" ;

No, that won't work.

You need to have Universal Email to make those updates.

I do have Universal Email

See page 4:

universal_email_gsg.pdf

You would be modifying the existing Email Object instead of adding one.

ok, I'm not sure how to get to the existing Email Object using Universal Email? I opened the users_registration.php in dreamweaver, went to the insert menu and selected webassist > universal email but it looks like its inserting a new one and not showing an existing one. Is that because the User Registration Solution Pak is in a sub folder and Universal email is looking in the root directory and does not see the WA_Universal_Email folder?

should I ask this question on the Universal Email forum?

You would look in the Server Behavior panel. The Universal Email behavior should be listed in that. You would double click on the behavior and it will open up the existing server behavior.
